This dissertation studies the concept of scale in the worldview of the Inca civilization, and was precipitated by the countless "miniature" objects made throughout the Pre-Columbian Andean world. Often relegated to the background of scholarship, scaled objects are not well understood and have exerted little influence on the academic understandings of the Incas.History of Art and Architecture

The ability to efficiently detect low-level light in the infrared above wavelengths of 1.7 μm is becoming increasingly important for many applications such as gas sensing, defence/geoscience ranging and clinical thermography. The III-V narrow gap semiconductor InAs, with a bandgap of 0.36 eV, is well known for its use as a conventional photodiode. The aim of this thesis was to design, build and test InAs devices for use as reverse biased avalanche photodiodes. In order to fabricate a lownoise detector, a passivation study was conducted. For the first time we report the achievement of high quality single crystal II-VI passivation layers on InAs mesa structures. Pre-growth surface oxide removal processes were developed to improve surface morphology of II-VI layers grown on InAs samples. ZnSe and ZnTe successfully terminate the InAs mesa devices preventing atmospheric oxidation. Low surface leakage currents are observed at low reverse bias and at room temperature for both materials. LIDAR at wavelengths greater than 2 μm was studied using these InAs mesa photodiodes, showing potential to take advantage of the low solar background at these wavelengths. For the first time, laboratory based LIDAR experiments, with ranges of around 0.5 metre stand-off distance, were performed with InAs n-i-p edge illuminated mesa photodiodes, used in linear multiplication mode. Time-of-flight measurements were demonstrated at wavelengths from 1.3 μm to 2.365 μm. A 6 mm ranging error was observed in these short range measurements.

CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOPontos quânticos (PQs) auto-organizáveis de InAs sobre InP, InGaAs, InGaAlAs utilizando-se substratos de InP foram crescidos pela deposição química de metal-orgânicos (MOCVD) e foram investigadas para fotodetectores. Para PQs de InAs crescidos sobre diferentes substratos de InP, têm-se que a presença de discordâncias é responsável pelo aumento na densidade planar dos PQs. O espectro de fotoluminescência (FL) das estruturas de InP/InxGa1-xAs/InAs/InP, com diferentes composições da camada ternária. Medidas com microscopia de força atômica (AFM) mostraram que os PQs mais altos são obtidos quando os mesmos são crescidos sobre uma camada de InxGa1-xAs com um descasamento de 1000ppm, e a altura decresce com o descasamento a partir deste valor. O espectro de FL dos PQs mostrou uma banda assimétrica, a qual envolve transições entre os níveis de energia dos PQs e pode ser decomposta em dois picos. Pico de energia mais alta desta banda foi observado para a amostra com PQs crescidos sobre uma camada de InxGa1-xAs casada e o pico foi deslocado para energias mais baixas para amostras tensionadas. Estruturas diferentes de PQ de InAs crescidas sobre uma camada de InGaAlAs casada com InP foram investigadas. Picos de fotocorrente extremamente estreitos foram observados, demonstrando um excelente potencial para sintonização estreita de comprimentos de onda. Foram desenvolvidas estruturas para detectar radiação superior à 10μm. Medidas de absorção mostrando uma dependência com a polarização mostraram eu as estruturas tem um confinamento total e são apropriadas para detecção sintonizável de radiação por incidência normal.
Self-assembled InAs quantum dots (QD) over an InP, InGaAs, InGaAlAs on InP substrates were grown by metal-organic chemical vapor deposition (MOCVD) and were investigated for quantum dot infrared photodetectors. For InAs QD over an InP buffer on different InP substrates. The results indicate that the presence of dislocations were responsible for the increase in the QD density. Photoluminescence (PL) spectra of InP/InxGa1-xAs/InAs/InP dot-in-a-well structures, with different compositions of the ternary layer. Measurements with atomic force microscopy showed that the largest QD height is obtained when the InAs QDs are grown on the InxGa1-xAs layer with a mismatch of 1000ppm, and the height decreases as the mismatch departs from this value. PL spectra of the QDs showed an asymmetric band, which involves transitions between dot energy levels and can be deconvoluted into two peaks. The highest energy PL peak of this band was observed for the sample with the QDs grown on top of the lattice-matched InxGa1-xAs and it shifted to lower energies for strained samples as the degree of mismatch increased. Different InAs quantum dot structures grown on InGaAlAs lattice matched to InP. Extremely narrow photocurrent peaks were observed, demonstrating great potential for fine wavelenght selection. Structures which can detect radiation beyond 10ìm were developed. Polarization dependence measurements showed that the structures have a zero- dimensional character and are suitable for detection of normal incidence light.

Pełny tekst źródłaStreszczenie:
Throughout the history of international law, there have been diverse interpretations about the nature of Francisco de Vitoria’s ideas. Among the most influential are Critical Legal Studies’ views. According to them, Francisco de Vitoria was the founder of an international legal discourse that was ethnocentric, pro-colonial and imperialistic. As an original contribution to the study of international legal ideas and contrary to CLS interpretations, this study demonstrates that Vitoria’s international normative doctrines were a 16th century effort to promote universal ideas, which had some ethnocentric and pro-colonial distortions. This study considers the importance of the philosophical, theological and anthropological dimensions of Vitoria’s international legal doctrines. It analyses Vitoria’s views on the status of indigenous people, especially the Inca, in the 16th century historical context of the Spanish conquest of indigenous nations. Vitoria’s doctrine on the human nature of indigenous people was the foundation for his recognition of the existence of political communities in the New World, and the participation of indigenous nations in the international community. Vitoria’s rejection of medieval doctrines, on the universal authority of the pope, was the foundation for his dismissal of Spanish legal instruments, such as the Requerimiento, which justified the conquest of the Inca and other indigenous nations. Vitoria’s doctrines on the natural law of nations’ norms of trade, travel and evangelism were a central aspect of his normative justification for the Spanish presence in the New World. In the 16th century Spanish intellectual context, these norms were not inherently ethnocentric. However, because of Vitoria’s disregard of the consequences of the implementation of these norms in the historical context of the Spanish-indigenous nations’ international relations, they could have served to justify the Spanish conquest and colonization of the New World. This study shows that Vitoria’s most compelling justification for the Spanish use of force was the ending of the indigenous custom of human sacrifice, which was a violation of the right to life in the internal jurisdictions of indigenous nations.

CAPES
This work aims to analyze the construction of the Inca past through the works Comments Reales de los Incas (1609) and Historia General del Peru (1617) by Inca Garcilaso de la Vega. As a mestizo and son of the New and Old World the author presents a very peculiar view of the universe. Often having their works understood as antagonistic to the travel reports produced during the sixteenth and seventeenth centuries, the intellectual effort in this paper focuses on the perspective of demonstrate the Gracilaso belief in a unity between the Hispanic and Inca worlds. Through historical mapping produced by Jorge Ca?izares-Esguerra author, the considerations presented by many contemporary intellectuals and internet research, we try to demonstrate the reception of the work Comments Reales de los Incas literate world in Europe, since the sixteenth century to the present.

Pełny tekst źródłaStreszczenie:
Synthetic aperture sonar (SAS) has become a well developed imaging technique for imaging shallow water environments. Aperture synthesis provides high along-track resolution imagery, with range independent resolution. However, mapping of the seafloor using traditional SAS is limited to a two-dimensional surface. To provide the third dimension (height), an interferometric synthetic aperture sonar (InSAS) is formed, comprising of two or more vertically displaced hydrophone arrays. Each of the interferometric receiver datasets are processed using standard SAS algorithms, with motion compensation and corrective processing applied equally to each channel, preserving the underlying interferometric time delays. By then estimating the time delay of the incoming wavefronts across the interferometric receiver array, the height of the seafloor can be inferred from the side-scan geometry of the system. The InSAS approach is similar to the radar equivalent (InSAR), however, significant differences in geometry and medium properties limit the applicability of InSAR algorithms to the sonar equivalent. A height estimate from interferometric data is formed by estimating the time difference between the receiver elements of the interferometric array. Therefore, for an accurate estimate of the time-delay, the signals of the receivers must contain significant 'common' information. Presented in this thesis is an analysis of coherence as applicable to an InSAS system. The coherence of an InSAS system can be decomposed into five 'coherence components': additive acoustic noise, footprint misalignment, baseline decorrelation, temporal decorrelation, and processing noise. Of these, it is shown footprint misalignment has the greatest effect for an InSAS system if it is not corrected for. The importance of maintaining high coherence between the receiver channels is presented; small losses in coherence from the ideal of unity will have a significant impact of the accuracy of the resulting height estimate. To reduce the sensitivity of the height accuracy losses, multiple estimates of the height can be formed from independent 'looks' of the scene. Combining all these estimates into one height estimate is shown to significantly improve the height estimate. The design and signal processing of an InSAS system is of high importance to the generation of high accuracy height estimates of the seafloor. Several parameters of design are explored, in particular the effect of aperture sampling. Low along-track aperture sampling rates are shown to cause a significant decrease in signal coherence, caused by the generating of 'grating lobes' from the synthetic aperture processing. Substantial improvements can be made by careful selection of transmitter and receiver element sizes, relaxing the requirements of a highly sampled aperture. An analysis of interpolation schemes on interferometric quality is also presented. The effect of footprint misalignment can be reduced by first resampling the data from each receiver onto a common ground-plane. However, this requires prior knowledge of the seafloor height, an unknown parameter before an interferometric height estimate is made. One possible method to form an initial height estimate is through the use of belief propagation, a technique applied from the field of stereo imaging. Belief propagation is used to estimate an initial height surface, albeit at discrete height intervals. This initial low resolution height surface can then be used to remap the data, partially eliminating the detrimental effects of footprint misalignment. The combination of all the independent estimates of the scene can be combined using maximum likelihood estimation. This framework allows the individual estimates to be combined into one overall cost function. Searching of the cost function for minimum cost yields a single interferometric time-delay estimate, from which a single height estimate can be inferred. This framework allows looks formed from many different sources to be combined, including multiple imaging frequency bands, and the use of more than one interferometric pair of receivers.

É possível que uma definição de uma gramática da forma subjacente na arquitetura Inca possa assistir na reconstrução arqueológica virtual de sítios destruídos. A análise das formas principais provavelmente permitiria fazer avanços no domínio do mundo da arquitetura Inca através da sua inserção no mundo digital. A altamente distinta e reconhecível arte e arquitetura Inca tende a ser consistente através dos séculos em todo o território andino e representou, de fato, uma afirmação de poder. Nesta tese foi desenvolvida uma gramática da forma simplificada especificamente para a arquitetura Inca. Os algoritmos gerados são básicos e independentes de plataformas, permitindo a futura implementação de sistemas CAD generativos mais duradouros e menos suscetíveis às mudanças nos programas computacionais. Geometricidade, padrões interconectados, plantas e demais representações ortogonais, cor e textura, reversão de padrões, espelhamento, repetição, compressão modular, derivações, rotação, simetria, razão, recombinação e êntase (ilusões óticas) são qualidades freqüentemente encontradas na arquitetura e arte andina e principalmente inca. Estas qualidades são de caráter "CAD - amigável" e podem ser integradas nas predições técnicas de reconstrução virtual, representando monumentos e possivelmente as artes antigas andinas sofisticadas, parcialmente danificadas ou substancialmente destruídas. ______________________________________________________________________________ ABSTRACT
The process of definition of a possible underlying shape grammar behind Inca architecture can assist in the virtual archaeological reconstruction of destroyed and partially destroyed sites; that is, to attempt to progress from the ancient to the digital realm. The highly distinctive and recognizable Inca architectural and art style tends to be consistent throughout the length of the Andes, and was in effect, a statement of power. This allows for the generation of fairly simple and straightforward algorithms which are used to develop shape grammars. These are and need to be independent of platforms and can be implemented in the future as CAD generative systems. They are designed so as not to be tied to one system. Geometricity, interlocking patterns, orthogonal layouts, colour and texture reversal, modular compression, derivations, rotation, mirroring, repetition, symmetry, proportion, ratios, recombination and the Andean version of 'entasis' are qualities frequently encountered in Andean art and architecture. These qualities can be considered 'CAD-friendly' and can be integrated into predictive digital virtual reconstruction techniques representing partially damaged and substantially destroyed ancient Andean monuments (and may also be applicable to some of the fine arts).

Pełny tekst źródłaStreszczenie:
This thesis describes an experimental study of the electronic properties of semiconductor heterostructure tunnel devices. InAs self-assembled quantum dots (QDs) are incorporated into the barrier layer of a GaAs/AlAs/GaAs tunnel diode. When a voltage, V, is applied across the device, we observe resonant features in the tunnel current, I, whenever an electron state in one of the qds comes into resonance with an occupied electron state in the emitter. We employ an electron state of a single qd as a spectroscopic probe of a two-dimensional electron system (2DES), from the Fermi energy to the subband edge [1]. For magnetic field B applied parallel to the current, we observe peaks in the I(V) characteristics corresponding to the formation of Landau levels in the 2DES. We obtain quantitative information about the energy dependence of the quasiparticle lifetime, Tqp, of the 2DES. We find that Tqp ~ 2.5 hbar=(Ef - E), in contrast with the expectation for a normal Fermi liquid, but in agreement with predictions for a Fermi liquid state of a disordered 2DES. Close to filling factor nu = 1 we observe directly the exchange enhancement of the g factor. This thesis also describes the design, realisation and measurement of a tunnel diode incorporating InAs QDs and a series of 4 planar electrostatic gates. By applying a bias to the gates, it is possible to selectively inject current into a particular QD. We use magneto-tunnelling spectroscopy to determine the energy levels of the ground and excited state of a single QD, and to map the spatial form of the wave functions of these states [2]. The effect of pressure on the resonant tunnelling of the QDs is also described. [1] P. C. Main et al., Phys. Rev. Lett. 84, 729 (2000) [2] R. J. A. Hill et al., Appl. Phys. Lett. 79, 3275 (2001)

A Web Semântica permite a divulgação de dados na Internet através de um formato comum com o objetivo de integrar ou combinar bases de dados provenientes de diversas fontes. O Instituto Nacional de Pesquisas da Amazônia - INPA possui várias coleções de dados, principalmente científicos, que podem ser divulgadas e utilizadas na pesquisa e desenvolvimento da Amazônia e para o progresso da ciência. O objetivo deste trabalho é investigar como a utilização das tecnologias da Web Semântica, dentre elas os recursos da ferramenta Rexplorator, pode melhorar o processo de pesquisa, através do processamento da semântica, das coleções de dados biológicos do instituto. A abordagem utilizada é de desenvolver casos de uso junto com os próprios pesquisadores, através de operações simples em cima dos modelos RDFS (Resource Description Framework Schema) das próprias bases. Os casos de uso poderão ser reutilizados por outros pesquisadores, inclusive de domínios de pesquisa diferentes. Neste processo de reutilização é possível que os casos de uso sejam customizados e evoluídos colaborativamente no próprio ambiente em que foram desenvolvidos. Como resultado do processo são geradas aplicações Web que abstraem os modelos RDF (Resource Description Framework) nos quais os dados estão representados tornando possível o acesso às informações por outros pesquisadores que não conhecem esses modelos. Essa facilidade de acesso, além de permitir consultas a bases semânticas por usuários leigos em um dado domínio de pesquisa, também visa permitir que pesquisadores possam realizar consultas transdisciplinares enriquecendo sua visão no desenvolvimento da pesquisa, bem como seu poder nas tomadas de decisões políticas, econômicas e sociais, e, consequentemente, uma melhor gestão do conhecimento.
The Semantic Web enables the dissemination of data on the Internet through a common format in order to integrate or combine databases from different sources. The National Institute for Amazonian Research (INPA) has several collections of data, mainly scientific, that can be disclosed and used in the research and development of the Amazon as well as for the advancement of science. The objective of this study is to investigate how the use of Semantic Web technologies, among them the tool Rexplorator, can improve the research process by processing the semantics in collections of biological data. Use cases are developed with input from INPA researchers. Queries are constructed based on RDFS (Resource Description Framework Schema) created for INPAs existing collections. Use cases can be reused by other researchers, including researchers from different fields. In this process of reuse, the customization and collaborative development of use cases is possible. The result of this process is the generation of Web applications that abstract the RDF model on which data are represented. Consequently, other researchers unfamiliar with the RDF model are also able to access information. In addition to enabling semantic queries in databases by lay users in a given field of research, this ease of access enables researchers to make transdisciplinary queries enriching their vision of research development, as well as their power in political, economic and social decision-making, and hence better knowledge management.

In the Inca Empire, the human body served as a symbol and mediator of cosmic structures and processes through its own structures and processes. The structures of the body with cosmological relevance included the duality of right and left and the integrated unity of the body as a whole, while the processes of the body included reproduction, illness and sensory perception. Inca myths and rituals both expressed and enacted this corporeal and cosmic order.With the arrival of the Spanish, the Incas were confronted with a radically different image of the body and the cosmos. The clash between the Spanish and Inca orders was experienced by the Incas as a disordering of the human and cosmic bodies. While the Spanish Conquest destroyed the Inca empire and imposed a new culture on its former inhabitants, however, many of the principles which ordered and interrelated the body and the cosmos in Inca cosmology have survived in the Andes to the present day.

San Jerónimo, a la entrada de la población, a la mano izquierda de la carretera
y hacia la calle Teja Huasi donde se encontraban los hornos para la cocción de
tejas. Dentro del perímetro que ocupaba este ayllu se encontraban la plaza
principal y la iglesia. Más arriba de los hornos se asentaban los miembros del
ayllu Aucaille. Los ayllus Chima y Raurau se hallaban a la derecha de la
carretera, desde el comienzo del poblado hasta casi la mitad de éste, donde se
encontraba la cruz de “chima raurau” empotrada a la pared de un canchón
contiguo al cementerio. Pasando esta cruz se encontraban las calles Sañuc,
Yacanora y Apumayta. (2005: 95-96) Hoy en día los nombres de las calles han
cambiado y en su lugar se han puesto los nombres de los héroes de la
Independencia. Poco queda de los antiguos ayllus reducidos en San Sebastián
en la época colonial.Tesis

Ce travail concerne l'etude experimentale et theorique des proprietes electroniques de puits quantiques fortement contraints inas/inp et inas/gaas. Les particularites de ces deux systemes sont, d'une part, le fort desaccord de maille (-3,2% pour inas/inp et -7,2% pour inas/gaas), et d'autre part, les faibles valeurs de l'energie de bande interdite et du couplage spin-orbite d'inas conduisant a des masses effectives peu elevees et a un couplage inter-bandes important. Des experiences de photoluminescence, d'absorption optique detectee thermiquement (aodt) et de reflectivite ont ete effectuees sur des puits quantiques simples inas/inp d'une a trois monocouches d'epaisseur, elabores par epitaxie en phase vapeur par la methode aux hydrures, et sur des multi-puits quantiques inas/gaas d'environ une monocouche d'epaisseur, realises par epitaxie sous jets moleculaires. Differentes transitions liees aux puits d'inas ont ete observees et la spectroscopie d'aodt a permis de mettre en evidence, pour la premiere fois dans le systeme inas/inp, la transition excitonique impliquant les trous legers. L'ajustement des estimations theoriques aux energies des transitions observees a conduit a la determination precise des decalages de bandes aux interfaces inas/inp et inas/gaas et a l'obtention du coefficient de segregation lie a la repartition de l'indium dans les multi-puits d'inas/gaas. La modelisation numerique des resultats experimentaux a necessite la mise en uvre de modeles incluant de facon satisfaisante les effets conjugues des fortes contraintes et des couplages entre bandes. En particulier, nous avons mis au point une procedure de calcul permettant la determination correcte des etats de valence dans un puits quantique contraint et incluant le couplage entre la bande des trous legers et la bande spin-orbite qui intervient par interaction #k. #p via d'autres bandes eloignees

Disertaciniame darbe nagrinėjamas InAs/AlSb medžiagų sistemos panaudojimas trumpabangių tarppajuostinių lazerių kūrimui. Buvo išplėtota molekulinių pluoštelių epitaksijos technologija, leidžianti auginti daugiaperiodines neįtemptas InAs/AlSb heterosandūras su mažu 1-2 atominių sluoksnių šiurkštumu. Buvo parodyta, jog InAs/AlSb medžiagų sistema yra tinkama kurti trumpabangiams kvantiniams kaskadiniams lazeriams, veikiantiems žemiau 4 µm bangos ilgio ribos. Buvo ištirtas kvantinių kaskadinių lazerių, turinčių tiek plazmoninius bangolaidžius su stipriai legiruotais InAs apdariniais sluoksniais, tiek ir mažo periodo InAs/AlSb supergardelių bangolaidžius, veikimas bei jų įtaka prietaiso parametrams. Šie sprendimai dėl bangolaidžių bei tolimesni aktyviosios terpės patobulinimai, naudojant piltuvėlio formos injektorių, leido sukurti didelio našumo prietaisus, galinčius veikti iki 420 K temperatūros, esant 3,3 µm bangos ilgio emisijai, ir pasiekti maksimalią optinę galią siekiančią 1 W kambario temperatūroje. Šios inovacijos leido sukurti ir InAs/AlSb kvantinį kaskadinį lazerį, emituojantį ~2,6 µm bangos ilgio spinduliuotę šiai dienai tai yra trumpiausią bangos ilgį spinduliuojantis tokio tipo prietaisas pasaulyje.Application of InAs/AlSb materials system for development of short-wavelength quantum cascade lasers is explored. Molecular beam epitaxy (MBE) technology allowing to grow multiperiodical unstrained InAs/AlSb heterostructures with roughness of 1-2 monolayers is developed. It is demonstrated that InAs/AlSb materials system is well-suitable for development of short-wavelength quantum cascade lasers operating below 4 µm wavelength. Lasers containing plasmon-enhanced waveguides as well as the short period InAs/AlSb superlattices as waveguides were designed, MBE-grown and studied. The effect of waveguide properties on the device parameters is revealed. Usage of these waveguides and innovations in laser active region introducing “funnel” injector allowed one to reach operation temperature 420 K at the emission wavelength of 3.3 µm. The obtained optical peak power exceeded 1 W per facet. The room temperature operation has been obtained at wavelength below 3 µm. As for wavelength range, applying the new active region design strategy and the short period InAs/AlSb superlattice spacers InAs based quantum cascade lasers emitting at the wavelengths as short as 2.63 µm were developed, which is today the shortest emission wavelength of the operation of semiconductor lasers based on the intersubband transitions.

Pełny tekst źródłaStreszczenie:
First discovered by Holm and Meissner in 1932, the superconducting proximity effect has remained a subject of experimental and theoretical interest. In recent years, it has been proposed that proximity effect in a semiconductor with large g-factor and spin-orbit coupling could lead to exotic phases of superconductivity. This thesis focuses on proximity effect in one of the prime semiconductor candidates -- InAs nanowires.
The first set of experiments investigates the superconducting phase-dependent tunneling spectrum of a proximitized InAs quantum dot. We observe tunneling resonances of Andreev bound states in the Kondo regime, and induce quantum phase transitions of the quantum dot ground state with gate voltage and phase bias -- the latter being the first experimental observation of its kind. An additional zero-bias peak of unknown origin is observed to coexist with the Andreev bounds states.
The second set of experiments extends upon the first with sharper tunneling resonances and an increase in the device critical field. By applying an external magnetic field, we observe spin-resolved Andreev bound states in proximitized InAs quantum dots. From the linear splitting of the tunneling resonances, we extract g-factors of 5 and 10 in two different devices.
The third set of experiments utilizes a novel type of epitaxial core-shell InAs-Al nanowire. We compare the induced gaps of these nanowires with control devices proximitized with evaporated Al films. Our results show that the epitaxial core-shell nanowires possess a much harder induced gap -- up to two orders of magnitude in sub-gap conductance suppression as compared to a factor of five in evaporated control devices. This observation suggests that roughness in S-N interfaces plays a crucial role in the quality of the proximity effect.
The fourth set of experiments investigates the gate-tunability of epitaxial half-shell nanowires. In a half-shell nanowire Josephson junction, we measure the normal state resistance, maximum supercurrent, and magnetic field-dependent supercurrent interference patterns. The gate dependences of these independent experimental parameters are consistent with one another and indicate that an InAs nanowire in good ohmic contact to a thin sliver of Al retains its proximity effect and is gate-tunable.Physics

The optical properties of InAs/GaSb heterostructures under applied magnetic fields are studied in experimental and theoretical detail. The InAs/GaSb system is a type-II "crossed-gap" system, where the valence band edge of GaSb lies higher in energy than the conduction band edge of InAs. This leads to a region of energy above the InAs conduction band where conduction and hole states mix. Thin-layer superlattices remain semiconducting due to confinement effects, but thick-layer superlattices experience charge transfer which leads to intrinsic carrier densities approaching 1012 cm-2 per layer. Existing multi-band modeling techniques based on the k·p formalism are discussed, and a method of solving superlattice band structure (the "momentum-matrix" technique) is presented. The quantizing effects of the superlattice layers and applied magnetic fields are investigated, and the selection rules for optical transitions are derived. Standard cyclotron resonance (CR) is used to study effective masses in InAs/GaSb structures. The heavy hole mass is found to be strongly orientation-dependent, with a mass in the [111] orientation reduced 25% from the [001] mass. The electron mass is found to be roughly isotropic with respect to growth orientation, but shows variation with the InAs width due to quantum confinement effects. CR of InAs/GaSb heterojunctions display hitherto unexplained oscillations in linewidth, intensity, and effective mass. A model is proposed which explains the oscillations, based on the intrinsic nature of the InAs/GaSb system. CR is performed on an InAs/GaSb heterojunction using a free-electron laser, where due to the high intensities (on the order of MW/cm2) the absorption process saturates. This saturation allows for a determination of non-radiative relaxation lifetimes, and through the energy dependence of these lifetimes the magnetophonon effect is observed, allowing a direct measurement of LO-phonon-assisted energy relaxation rates. Coupling is introduced into the standard CR experiment, either by tilting the sample with respect to the magnetic field, or by applying a metal grating to the surface. These coupled CR experiments have striking qualitative results which allow for determination of subband separation energies and coupling matrix elements. Photoconductivity experiments are performed on thin-layer (semiconducting) superlattices, showing optical response at far-infrared wavelengths (5-20 μm). The results are compared with k·p calculations. One sample is processed for vertical transport, in which conduction occurs perpendicular to the superlattice layers. Strong optical response from this sample indicates the viability of InAs/GaSb-based far-infrared detectors. The momentum-matrix technique is used to predict optimum parameters for semiconducting superlattices with band gaps in the far-infrared. Semimetallic structures are studied via a multi-band self-consistent model, with results corroborating with and extending previous work. Intrinsic structures under applied magnetic field are modeled theoretically for the first time.

Self-assembled III-V quantum dots (QDs) have been intensely studied for potential applications in solar cell (SC) devices in order to increase power conversion efficiency. Due to their quantum confinement of carriers, QDs have been proposed as a means of implementing the intermediate band solar cell (IBSC). The IBSC concept is characterised by in an increase in photocurrent and a preservation of output voltage, resulting from an enhanced sensitivity to the solar spectrum. The work reported in this thesis is concerned with the development of InAs QDs in GaAs p-i-n solar cell structures, with the aim of realising of an IBSC. The work involves the design, epitaxial growth by molecular beam epitaxy (MBE), device processing and characterisation of the QDSCs. This thesis first investigates InAs/InGaAs dot-in-a-well (DWELL) solar cell structures grown under different conditions. The use of a high-growth-temperature GaAs spacer layers is demonstrated to significantly enhance the performance of the multilayer DWELL solar cells. Threading dislocations were observed for a 30-layer QD structure with GaAs spacer layers grown at a low temperature (510 oC). By growing the GaAs spacer layer at a higher temperature (580 oC), the formation of threading dislocations were suppressed, resulting in enhanced optical properties. The thesis then goes on to address the main challenges facing QD IBSCs, that is, the reduction in open-circuit voltage and the lack of significant increase in short-circuit current. To eliminate the wetting layer and enhance the open-circuit voltage of the QD solar cell, an AlAs cap layer technique was used. This resulted in an enhancement of the open-circuit voltage of a 20-layer InAs/GaAs QDSC from 0.69 V to 0.79 V. Despite a slight reduction in short-circuit current, for the QDSC with AlAs cap layer, the enhancement in the open-circuit voltage was enough to ensure that its efficiency is higher than the QDSC without AlAs cap layers. In an attempt to enhance the short-circuit current, an antimony-mediated growth approach was used to grow high-density QDs. After optimisation of the growth temperature and InAs coverage, a very high in-plane QD density of 1 1011 cm-2 was achieved by applying a few monolayers of antimony prior to QD growth. Compared with a reference QDSC without the incorporation of antimony, the high-density QDSC demonstrates a distinct improvement in short-circuit current from 7.4 mA/cm2 to 8.3 mA/cm2. This result shows that a significant increase in short-circuit current could potentially compensate for the drop in open-circuit voltage observed in InAs/GaAs QD solar cells. Ongoing work on the development of QDSCs with both AlAs capping and antimony-mediated growth have resulted in the simultaneous elimination of the wetting layer and increase in QD absorption in a single device. Overall, the studies in this thesis present important implications for the design and growth of InAs/GaAs QD solar cell structures for the implementation of IBSCs.

Plantea que en el sitio arqueológico “El Portillo”, ubicado en la zona de Carapongo, del valle bajo del Rímac, corresponde a un modo de asentamiento de tipo aldeano, ocupado por población serrana de origen Chaclla, durante el período Horizonte Tardío. Para ello fue necesario identificar a que fenómenos sociales corresponde la cultura material hallada en el sitio arqueológico. Del mismo modo se identificó el modo de asentamiento y función y la cronología a la que corresponde “El Portillo”. Nuestros estudios revelaron que el modelo de asentamiento representado por El Portillo, corresponde a un fenómeno social exógeno a la tradición cultural costeña. Por lo cual podemos concluir que se trata de población foránea, que no comparte la tradición cultural costeña. El Portillo presenta un trazado de tipo irregular aglutinado y las excavaciones de los recintos revelaron contexto de carácter doméstico, con capas de basura apisonadas en la superficie. Así mismo estas evidenciaron consistentemente una sola y continua ocupación. La correlación de los tipos alfareros identificados con la secuencia local de la costa central y con las publicaciones especializadas, permiten observar que estos se relacionan claramente con los estilos correspondientes al Horizonte Tardío. Para identificar a que grupo social acudimos al modelo de asentamiento que no guardan relación con la tradicional arquitectura costeña. Se trataría entonces de población no local asentada en la zona de Carapongo. Ello concuerda con la información etnohistórica que nos remite siempre a una población serrana de origen Chaclla asentada en la zona de Carapongo.Tesis

La presente tesis analiza los roles femeninos en el Tahuantinsuyo y su importancia para el establecimiento de esta sociedad. Para el desarrollo de este tema, ha sido de suma importancia analizar el mito de Los Cuatro Hermanos Ayar, pues si bien existen otros mitos andinos, en este la participación femenina es de especial relevancia. Inclusive, se encuentra la participación de cuatro mujeres míticas: Mama Ocllo, Mama Huaco, Mama Cora y Mama Auca. Asimismo, se puede hallar muchas manifestaciones de la dualidad, que es un aspecto fundamental del Tahuantinsuyo.
El objetivo de este trabajo no es hallar datos históricos o historizar el mito, sino brindar una nueva perspectiva de análisis. Puesto que si bien se han utilizado crónicas para diversas investigaciones, la lectura concienzuda de los mitos es fundamental para el análisis histórico, ya que en ellos se pueden hallar expresiones de la cosmovisión andina, que se plasma en la organización geográfica, social, las relaciones de poder, los roles (masculinos y femeninos) y política del Tahuantinsuyo.
Por último, en la presente tesis se hace hincapié en el análisis del establecimiento de los roles femeninos, para a partir de este poder mostrar cómo las mujeres constituyen un componente fundamental en la consolidación del incario. Cabe resaltar, que la su actuación no siempre fue pasiva, si no que las mujeres incas tuvieron injerencia directa en diversos aspectos tales como el social, político, religioso y económico.Tesis

Aimara as the Inca Official LanguageAccording to traditional prehispanic Andean history, the official tongue of the Incas was Quechua, a language whose craddle is assumed to have been the Cuzco area. In view of current Andean historical linguistics, however, it all leads to the conclusion that Quechua couldn‘t have originated in the Cuzco region, since at the time of the beginings of the Inca empire, the language spoken there was Aimara, which in turn had spread southeasthward, coming from the Central Andes. In the present paper, documentary, onomastics, and linguistic proper evidences are advanced to prove that the official language of the Incas, at least up to the reign of Tupac Inca Yupanqui, was Aimara and not Quechua.Según la visión tradicional de la historia prehispánica, la lengua oficial de los incas habría sido el quechua, lengua que, a su vez, se habría originado en la región cuzqueña. De acuerdo con los estudios de lingüística histórica andina, todo conduce a pensar que, en verdad, el quechua no pudo haberse originado en el Cuzco, pues en dicha región, al tiempo en que se formaba el imperio, se hablaba aimara, lengua procedente de los Andes Centrales. En este trabajo presentamos evidencias de tipo documental, onomástico y lingüístico propiamente dicho que demuestran que los incas tenían el aimara como lengua oficial hasta por lo menos el gobierno de Tupac Inca Yupanqui.

La presente investigación se encuentra focalizada en el estudio de dos tipos de diseños iconográficos pertenecientes al subestilo alfarero inca Cuzco Policromo Figurado (Rowe 1944): los personajes femeninos con toca cefálica (PFTC) y los personajes masculinos emplumados (PME).
Tras introducir al lector dentro de la problemática del estilo figurativo incaico, caracterizándolo tanto espacial como cronológicamente, es desarrollado el análisis de ambas modalidades de diseños. Si bien la aproximación empleada sigue en gran medida el método iconológico propuesto por Erwin Panofsky (1955) para el estudio de obras de arte, difiere de éste al recurrir a la información contextual de las materiales incorporándola como un importante referente interpretativo.
La revisión de referencias etnohistóricas y etnográficas, por consiguiente, se ve complementada con datos contextuales que facilitan el reconocimiento de la identidad social de los personajes representados iconográficamente y la naturaleza de las acciones ejecutadas por éstos. De ese modo se logra identificar la representación de acllaconas (femeninos y masculinos) ejecutando diversos ritos, entre los que se incluyen prácticas de culto ancestral y la producción ritualizada de bienes.
En la última parte de la tesis se evalúan tres puntos críticos en la investigación: a) la participación de los especialistas religiosos en la producción de cerámica inca con iconografía figurativa (modelo acllacona-artesano); b) el rol cumplido por este tipo de representaciones en el contexto de uso en que era exhibida; y, por último, c) la suerte experimentada por estos diseños una vez ocurrida la conquista española e iniciada la evangelización católica.Tesis

Cette figure de l'alterite va s'organiser autour de codes de la comprehension de l'autre, herites de traditions mythologiques anciennes: il s'agit des mythographies des monstres (definies par des auteurs classiques des antiquites grecque et romaine), et des mythographies des pays imaginaires (atlantide, el dorado. . . ). La fusion de ces figures de l'alterite donnera une grille de lecture a un nouveau continent qui, pour l'occidental, n'en a pas encore. Ces elements qui font la perception de l'autre constituent ensemble une ideologie de l'alterite. C'est le recit de voyage de colon qui servira ici de base a une telle perspective. Les decouvreurs, une fois devenus conquerants, vont alors elaborer une serie de regles de la comprehension de l'autre-indien. L'ensemble reposera sur la cupidite, la quete du pouvoir, la propaChristopher colombus discovery in 1492 will impose a thorough re-definition of man and the world to christian western europe. By enlarging the limits of the known world, it will first enable people to draw anew the cosmographers'maps. The enclosed world will be open, vast and perhaps boundless. But it is chiefly the outcome of the journey wich, in a deep and irrevocable way, will question the certainties about the spaces of life of human social groups. This outcome is the encounter with the other; this other standing for the lands of the new world as well as for their inhabitants, and who will be called "indians" by colombus. The latter will first be seized in his apparent reality, immediately perceptible. This physical apparence of otherness will become organized round codes of the understanding of the other, inherited from ancient mythological traditions wich refer to the mythographies of monsters (defined by classical authors of greek and roman, antiquities) and the mythographies of imaginary lands (atlantis, el dorado. . . ). The blending of these faces of otherness will give a new continent a reading code, wich is not yet the case for western europe, at that time. These elements wich constitute the perception of the other, assemble together to make an ideology of otherness. It is the text of columbus' journey account that will be used as a basis for such perspective. The discoverers once they became conquerors, will then work out a

Tesis para optar al grado de Magíster en Historia mención Etnohistoria.El presente trabajo de investigación se sitúa en el territorio históricamente conocido y denominado como el Despoblado de Atacama. Desde las primeras crónicas y documentación colonial, el llamado “Despoblado de Atacama” o el “Gran Despoblado”, fue definido como el territorio más árido, inhóspito, hostil e inhabitable de toda la región desértica del actual norte chileno. Diferenciándolo de los oasis y valles de las zonas de San Pedro de Atacama y de Copiapó, ubicadas en sus extremos, convencionalmente se lo señaló desde el siglo XVI, como el área que se extendía entre el sur del Salar de Atacama (aproximadamente desde la localidad de Peine) y el inicio de los valles del río Copiapó, abarcando prácticamente todo el espacio comprendido desde la costa hasta los faldeos y borde puneño de la cordillera de los Andes.

L'émergence d'une une nouvelle classe de matériaux, des isolants topologiques, a stimulé un vaste champ de recherche. Bismuth, un élément du groupe V du tableau périodique, est un des ingrédients clé d'une famille d'isolants topologiques. Pour des applications dans la technologie des composants électroniques, il est essentiel de maîtriser la préparation des matériaux en couches minces. Dans ce travail de thèse, nous avons étudié la croissance et la structure électronique de bismuth sur les surfaces (100) et (111) de semi-conducteur III-V InAs.Déposition de Bi sur la surface InAs(100) résulte en une auto-organisation de Bi qui forme des lignes de taille atomique. On montre que le bismuth interagit extrêmement faiblement avec la surface car la structure d'origine de la surface propre de l'InA(100) reste intacte. L'étude de la bande valence montre la présence d'états résonants fortement dépendants de l'énergie de photons et de la polarisation de la lumière, en cohérence avec la structure quasi unidimensionnelle de la surface.La spécificité de la surface InAs(111) est qu'elle a deux terminaisons différentes: par In, (face A) et par As, (face B). Les deux faces présentent des reconstructions différentes. Par la photoémission des niveaux de coeur nous avons montré une différence de réactivité chimique entre les faces A et B. La croissance de Bi sur la face A résulte en un monocristal de haute qualité pour les films à partir de 10 monocouches. Par contre, lors du dépôt de premières couches, la face B montre une croissance en îlots et un bon monocristal est obtenu seulement pour des films d'au moins de 50 monocouches.Pour la même face, A ou B, nous avons observé des différences de croissance plus subtiles entre les surfaces préparées soit par le bombardement ionique et des recuits soit par l'épitaxie par jets moléculaires.La photoémission résolue en angle a permit de caractériser la dispersion des bandes dans les films de Bi. La dispersion est tout à fait comparable au cristal massif de Bi. La dernière étape consistait à étudier la structure électronique d'un monocristal de Sb déposé sur le film de Bi.Les surfaces propres de InAs(111)A et InAs(111)B présentent une courbure de bande qui résulte en formation d'une couche d'accumulation d'électrons. En déposant le Bi sur ces surfaces, la couche d'accumulation est préservée, elle est même amplifié, car Bi agit comme le donneur dans l'InAs.La couche d'accumulation se traduit par un confinement quantique des électrons, mesurable par la photoémission résolue en angle.Mots clés :Structure électronique de surface, ARPES, semimétal, courbure de bande, Gaz-2D, Bismuth, Sb, InAs(111)A, InAs(111)B, puits quantique, surface Fermi, couches mincesA new class of material is coming up, Topological Insulators, have opened a wide field of research. Bismuth, an element of group V of periodic table, is one of the key ingredient of this Topological Insulators family. With the aim of improving technological applications, especially the electronic compounds, it is of most importance to control the preparation of thin films materials. Within this Phd work, we studied the growth and Bismuth electronic structure on (100) and (111) semiconductor III-V InAs surfaces.Bi deposition on InAs(100) surface result of a Bi self-assembly which forms lines at atomic scale. We show Bi interact extremely weakly with the surface because the beginning structure of clean InAs(100) surface stay unharmed. The study of valence band sheds light on the existence of resonant states strongly photon energy dependent and also depend on the light polarization, consistent with almost one dimensional structure surface.InAs(111) surface specific feature is that it has both surface ending different : In ending, (face A) and As ending, (face B). The both faces pointed out distinguishable reconstructions. By the core-level photoemission we identified a chemical reactivity difference taking place between A and B faces. Bi growth on A-face tend to be a high quality monocrystal for those films from a thickness of 10 monolayers. On the other hand, during the deposition of first layers, the B-face show an island growth and a good monocrystal is obtained only available for films with 50 monolayers at least.For the same face, A or B, we have seen some growth discrepancies more subtle between prepared surfaces either by ionic bombardment and annealing (IBA) either by molecular beam epitaxy (MBE).The angular resolved photoemission allowed to identify the band dispersion inside of this Bi films. The dispersion is absolutely relative to the bulk Bi crystal. The final step involved the study of Sb monocrystal electronic structure deposited onto Bi film.Clean InAs(111)A and InAs(111)B surfaces indicate a band bending which result in the accumulation electron charge formation. With depositing Bi onto these surfaces, the accumulation layer would be kept, it is also increased, given that Bi acts as a donor-like in InAs. The accumulation layer is characterized by an electron quantum confinement, measurable by angle resolved photoemission.Keywords:Electronic structure surface, ARPES, semimetal, band bending effect, 2DEG, Bismuth, Sb, InAs(111)A, InAs(111)B, quatum wells, Fermi surface, thin films
