Full textInAs and Bi1-xSbx nanowires with their distinct material properites hold promises for nanoelec- tronics and quantum computing. While the high electron mobility of InAs is interesting for na- noelectronics applications, the 3D topological insulator behaviour of Bi1-xSbx can be used for the realization of Majorana Fermions based qubit devices. In both the cases improving the quality of the nanoscale material is mandatory and is the primary goal of the thesis, where we study CMOS compatible InAs nanowire integration on Silicon and where we develop a new nanoscale topological insulator. For a full CMOS compatiblity, the growth of InAs on Silicon requires to be self-catalyzed, fully vertical and uniform without crossing the thermal budge of 450 °C. These CMOS standards, combined with the high lattice mismatch of InAs with Silicon, prevented the integration of InAs nanowires for nanoelectronics devices. In this thesis, two new surface preparations of the Silicon were studied involving in-situ Hydrogen gas and in-situ Hydrogen plasma treatments and leading to the growth of fully vertical and self-catalyzed InAs nanowires compatible with the CMOS limitations. The different growth mechanisms resulting from these surface preparations are discussed in detail and a switch from Vapor-Solid (VS) to Vapor- Liquid-Solid (VLS) mechanism is reported. Very high aspect ratio InAs nanowires are obtained in VLS condition: upto 50 nm in diameter and 3 microns in length. On the other hand, Bi1-xSbx is the first experimentally confirmed 3D topololgical insulator. In this new material, the presence of robust 2D conducting states, surrounding the 3D insulating bulk can be engineered to host Majorana fermions used as Qubits. However, the compostion of Bi1-xSbx should be in the range of 0.08 to 0.24 for the material to behave as a topological insula- tor. We report growth of defect free and composition controlled Bi1-xSbx nanowires on Si for the first time. Different nanoscale morphologies are obtained including nanowires, nanoribbons and nanoflakes. Their diameter can be 20 nm thick for more than 10 microns in length, making them ideal candidates for quantum devices. The key role of the Bi flux, the Sb flux and the growth tem- perature on the density, the composition and the geometry of nanoscale structures is investigated and discussed in detail

Full textLe but de ce travail est d’acquérir les connaissances requises pour la conservation et la gestion durable des ressources génétiques de l’espèce. Trois objectifs ont été définis :(i) étudier la phylogéographie de l’espèce, (ii) étudier sa variabilité morphologique et génétique au Bénin et (iii) caractériser sa biologie de reproduction. En amont de ces travaux, nous avons développé onze marqueurs microsatellites nucléaires chez P. butyracea (chapitre 2). Ils ont été utilisés pour l’étude de la phylogéographie et la diversité génétique de P. butyracea (chapitres 3 et 5), ainsi que pour étudier la dépression de consanguinité et les paramètres de son système de reproduction (chapitre 7).
La caractérisation de la répartition spatiale des lignées génétiques de régions intergéniques de l’ADN chloroplastique et de l’ADN ribosomal (ITS) a détecté deux lignées génétiques allopatriques entre le Haut et le Bas-Guinéen, indiquant une forte différenciation génétique et un signal phylogéographique. L’analyse des microsatellites détecte trois pools géniques correspondant aux trois régions étudiées (Haute Guinée, Dahomey Gap et Basse Guinée). La diversité génétique est faible dans le Dahomey Gap, modérée dans le Haut-Guinéen et élevée dans le Bas-Guinéen. Ces résultats indiquent une séparation très ancienne des populations d’Afrique centrale et d’Afrique de l’ouest, alors que celles du Dahomey Gap pourraient résulter des forêts denses humides de l’Afrique de l’ouest lors de la période Holocène humide africaine. Dans ce couloir sec, les populations ont subi une forte dérive génétique, potentiellement due à des évènements de fondation. Au Bénin, deux groupes éco-morphologiques ont été détectés suivant un gradient nord-sud, contrastant avec deux pools géniques présentant une distribution est-ouest.
P. butyracea est une espèce auto-compatible majoritairement allogame. La corrélation de paternité est plus élevée aux niveaux intra-fruit vs. inter-fruits, et au sein d’une population de petite taille vs. de grande taille. Les principaux pollinisateurs au Bénin sont deux oiseaux (Cyanomitra verticalis, Cinnyris coccinigastrus) et trois abeilles (Apis mellifera, Meliponula togoensis, Hypotrigona sp.). La productivité totale en fruits augmente en fonction de l’âge de l’arbre et varie en fonction de l’année, atteignant un pic pour les arbres ayant un diamètre de 60-80 cm. Les graines sont récalcitrantes et ont une teneur en eau de 42.5 ± 2.9 %.
L’analyse des paramètres de reproduction et de diversité génétique, associés aux facteurs écogéographiques, nous a permis de proposer un échantillon de neuf populations représentatives de la diversité à l’échelle du Bénin, dans la perspective d’une conservation in situ. Le succès de celle-ci dépendra des efforts conjugués des communautés locales, de la recherche forestière et de la définition d’un cadre législatif par le politique pour la protection des habitats. La conservation ex situ est envisagée sous forme d’un verger rassemblant diverses origines, présentant l’intérêt supplémentaire de permettre d’étudier les contributions de la diversité génétique et de la plasticité phénotypique à la variation phénotypique. / Pentadesma butyracea Sabine is one of the four species of the endemic genus Pentadesma in Africa. The species is distributed from Sierra Leone to Gabon in two major types of habitats: the discontinuous and dense Guineo-Congolian rainforests (Upper and Lower Guinea) and the Sudanian domain of the dry corridor of Dahomey (considered as a barrier to the exchange of genes and species between Upper and Lower Guinea). In the latter, the species is found in gallery forests and plays a vital role in the socio-economic livelihood of local communities due to the various resources and services that provide its products (food, medicine and traditional, etc.). However, pressure from many sources including the collection of seeds to make butter, habitat fragmentation and its destruction for market gardening, inadequate agricultural practices, fires, are serious threats to the species.
The aim of this work was to acquire appropriate knowledge for the conservation and sustainable management of genetic resources of the species. Three objectives were defined (i) study the phylogeography of the species; (ii) evaluate its morphological and genetic variability in Benin; and (iii) characterize its reproductive biology. In a preliminary work, eleven nuclear microsatellite markers of P. butyracea were developed (Chapter 2). They were used for the study of phylogeography and genetic diversity of P. butyracea (chapters 3 and 5), and to study the inbreeding depression and parameters of its breeding system (Chapter 7).
The characterization of the genetic lineages and their spatial distribution using intergenic regions from chloroplast DNA and ribosomal DNA (ITS) region detected two allopatric genetic lineages between Upper and Lower Guinea, indicating a high genetic differentiation and a phylogeographic signal. Microsatellite markers allowed us to detect three genepools matching with the three studied regions (Upper Guinea, Dahomey-Gap and Lower Guinea). Genetic diversity was low in the Dahomey Gap, moderate in Upper Guinea and high in Lower Guinea. These results indicate an ancient separation of populations from Central and West Africa, while those from Dahomey Gap could originate West African rainforests (Upper Guinea) during the African humid Holocene period. In this dry corridor, populations experienced high genetic drift, possibly due to founding events. In Benin, two eco-morphological groups were detected following a north-south gradient, contrasting with two gene pools presenting an east-west distribution.
Pentadesma butyracea is a self-compatible, mainly allogamous species. The correlation of paternity was higher within-fruit vs. among-fruits, and in population of small size vs. large size. The main pollinators in Benin are two birds (Cyanomitra verticalis, Cinnyris coccinigastrus) and three bees (Apis mellifera, Meliponula togoensis, Hypotrigona sp.). Total productivity in fruit increases with tree age and varies yearly, reaching a peak for trees of 60-80 cm of diameter class. Seeds are recalcitrant (i.e. they cannot be conserved at low temperature), having a water content of 42.5 ± 2.9% at maturity.
The analysis of reproduction and genetics parameters, associated with eco-geographic factors, enabled us to select nine populations representative of the diversity in Benin, from the perspective of in situ conservation. The success of the latter will depend on combined efforts of local communities, forest research and an adequate legislative framework for the protection of habitats. Ex situ conservation is envisaged as an orchard assembling various origins, and would have the additional advantage of allowing to study the contribution of genetic diversity and phenotypic plasticity to phenotypic variation.

Full textA renewed focus on generalised pollinator systems has inspired a conceptual framework which highlights that spatial and temporal interactions among plants and their assemblage of pollinators can vary across the individual, population, regional and species levels. Pollination is clearly a dynamic interaction, varying in the number and interdependence of participants and the strength of the outcome of the interaction. Therefore, the role of variation in pollination is fundamental for understanding ecological dynamics of plant populations and is a major factor in the evolution and maintenance of generalised and specialised pollination systems. My study centred on these basic concepts by addressing the following questions: (1) How variable are pollinators in a generalised pollination system? To what degree do insect visitation rates and assemblage composition vary spatially among populations and temporally among flowering seasons? (2) How does variation in pollinators affect plant reproductive success? I chose to do this using a model system, Trachymene incisa subsp. incisa (Apiaceae), which is a widespread Australian herbaceous species with simple white flowers grouped into umbels that attract a high diversity of insect visitors. The Apiaceae are considered to be highly generalist in terms of pollination, due to their simple and uniform floral display and easily accessible floral rewards. Three populations of T. incisa located between 70 km and 210 km apart were studied over 2-3 years. The few studies investigating spatial and temporal variation simultaneously over geographic and yearly/seasonal scales indicate that there is a trend for more spatial than temporal variation in pollinators of generalist-pollinated plants. My study showed both spatial and temporal variation in assemblage composition among all populations and variation in insect visitation rates, in the form of a significant population by year interaction. However, removing ants from the analyses to restrict the assemblage to flying insects and the most likely pollinators, resulted in a significant difference in overall visitation rate between years but no difference in assemblage composition between the Myall Lakes and Tomago populations. These results indicate more temporal than spatial variation in the flying insect visitor assemblage of T. incisa. Foraging behaviour provides another source of variation in plant-pollinator interactions. Trachymene incisa exhibits umbels that function as either male or female at any one time and offer different floral rewards in each phase. For successful pollination, pollinators must visit both male and female umbels during a foraging trip. Insects showed both preferences and non-preferences for umbel phases in natural patches where the gender ratio was male biased. In contrast, insects showed no bias in visitation during a foraging trip or in time spent foraging on male and female umbels in experimental arrays where the gender ratio was equal. Pollinator assemblages consisting of a mixture of different pollinator types coupled with temporal variation in the assemblages of populations among years maintains generalisation at the population/local level. In addition, spatial variation in assemblages among populations maintains generalisation at the species level. Fire alters pollination in T. incisa by shifting the flowering season and reducing the abundance of flying insects. Therefore, fire plays an important role in maintaining spatial and temporal variation in this fire-prone system. Although insect pollinators are important in determining the mating opportunities of 90% of flowering plant species worldwide, few studies have looked at the effects of variation in pollinator assemblages on plant reproductive success and mating. In T. incisa, high insect visitation rates do not guarantee high plant reproductive success, indicating that the quality of visit is more important than the rate of visitation. This is shown by comparing the Agnes Banks and Myall Lakes populations in 2003: Agnes Banks received the highest visitation rate from an assemblage dominated by ants but produced the lowest reproductive output, and Myall Lakes received the lowest visitation rate by an assemblage dominated by a native bee and produced the highest seedling emergence. Interestingly, populations with different assemblage composition can produce similar percentage seed set per umbel. However, similar percentage seed set did not result in similar percentage seedling emergence. Differences among years in reproductive output (total seed production) were due to differences in umbel production (reproductive effort) and proportion of umbels with seeds, and not seed set per umbel. Trachymene incisa is self-compatible and suffers weak to intermediate levels of inbreeding depression through early stages of the life cycle when seeds are self-pollinated and biparentally inbred. Floral phenology, in the form of synchronous protandry, plays an important role in avoiding self-pollination within umbels and reducing the chance of geitonogamous pollination between umbels on the same plant. Although pollinators can increase the rate of inbreeding in T. incisa by foraging on both male and female phase umbels on the same plant or closely related plants, most consecutive insect movements were between plants not located adjacent to each other. This indicates that inbreeding is mostly avoided and that T. incisa is a predominantly outcrossing species, although further genetic analyses are required to confirm this hypothesis. A new conceptual understanding has emerged from the key empirical results in the study of this model generalised pollination system. The large differences among populations and between years indicate that populations are not equally serviced by pollinators and are not equally generalist. Insect visitation rates varied significantly throughout the day, highlighting that sampling of pollinators at one time will result in an inaccurate estimate and usually underestimate the degree of generalisation. The visitor assemblage is not equivalent to the pollinator assemblage, although non-pollinating floral visitors are likely to influence the overall effectiveness of the pollinator assemblage. Given the high degree of variation in both the number of pollinator species and number of pollinator types, I have constructed a model which includes the degree of ecological and functional specialisation of a plant species on pollinators and the variation encountered across different levels of plant organisation. This model describes the ecological or current state of plant species and their pollinators, as well as presenting the patterns of generalisation across a range of populations, which is critical for understanding the evolution and maintenance of the system. In-depth examination of pollination systems is required in order to understand the range of strategies utilised by plants and their pollinators, and I advocate a complete floral visitor assemblage approach to future studies in pollination ecology. In particular, future studies should focus on the role of introduced pollinators in altering generalised plant-pollinator systems and the contribution of non-pollinating floral visitors to pollinator assemblage effectiveness. Comparative studies involving plants with highly conserved floral displays, such as those in the genus Trachymene and in the Apiaceae, will be useful for investigating the dynamics of generalised pollination systems across a range of widespread and restricted species.

Full textThe competitiveness-chasing in which industrial manufactures are involved, leads to an exponential increase in the number of functionalities per chips, as well as reducing their unit cost, which results in a continuous decrease of their size. To achieve this, DSA (Directed Self-Assembly) of block copolymers, combines conventional lithography techniques with the molecular-scale organizational properties of copolymers. In this framework, the overall objective of this thesis is to evaluate the industrialization potential of the DSA process by graphoepitaxy for contact hole shrink and contact multiplication applications. In particular, it is necessary to demonstrate the ability of this technique to meet the ITRS specifications in terms of CD uniformity, misalignment and hole open yield. A first study on contact shrink, based on the impact of material properties, surface affinity and guiding feature size, allows us to understand the mechanisms involved in the appearance of defects. A second part of the study deals with contact multiplication. To address this application, two types of guides have been studied: elliptical guiding patterns and more complex ones called "peanut". The study of the process window in terms of process parameters such as annealing time and temperature, but also commensurability was conducted. Particular attention was paid to guide size variation and its impact on DSA final pitch. Experimental data from this study were correlated with simulations. The success criteria are based on the lithographic performances that must be judged through advanced metrology. The development of a specific metrology to measure the placement error of contacts as well as their pitch was conducted

Full textThis thesis describes the study of the reactivity of boron compounds and the O-alkylation of aromatic alcohols. The use of boronic derivatives increased considerably over the past decades. There are used as cross-coupling partners in the Suzuki reaction and for 1,4 rhodium-catalyzed addition reaction. The nucleophilic nature of these compounds was induced by the C-B bond polarization. This peculiar reactivity was studied for the C-F bond formation. The use of Selectfluor® as fluorinating agent leads to good yields. Nevertheless, the polarity of the C-B bond could be reversed by oxidative nucleophilic substitution. Thus, C–N bond could be formed from nitriles and potassium trifluoroborate salts promoted by Cu(OAc)2 in the presence of BF3.OEt2. Due to the importance of ether chemistry in organic synthesis, the O-alkylation of phenol derivatives was achieved in the laboratory. From a stoichiometric amount of Lewis acid, BF3.OEt2, a catalytic system was developed involving cerium triflate. Then, the focus on green chemistry led to use a heterogeneous catalyst.

SRAM (Static Random Access Memory) is a dominating at type of volatile memory, widely used in CPU registers, CPU caches, and various kinds of buffers with the characteristics of fast read/write access time and infinite read/write endurance. Because SRAM is a pure logic circuitry composed of cross-coupled inverters, it is embedded in logic CMOS process to further reduce the cost in packaging. As process technology scales, threshold voltage of the transistors in SRAM cells must decreases for the need of supply voltage scaling while variation of threshold voltage increases as a result of dopant fluctuation and size fluctuation in minimization of critical dimensions. These fluctuations must be minimized or some soft errors might happen to cause read/write mistakes when operates. In this work, we introduce a new logic compatible OTP (One-Time Programmable) Memory made up of SAN (Self-Aligned Nitride) structure to combine with SRAM cells. Through blanket programming operation and self-convergent characteristics of the OTP cell, process variations can be effectively suppressed in the new SRAM to improve SNM (Static-Noise Margin). The read failure rate due to static noise can be reduced. Therefore, the variation caused by process can be solved by blanket trimming operations.

During the progression of integrated system on chip, the embedded nonvolatile memory (NVM), which does not need extra masks and to be fabricated by standard complementary metal oxide semiconductor (CMOS) process have been widely studied. Though there are many technologies and designs have been studied and developed for logic NVM applications, but until now, there is not an overall solution which can serve high program and erase performance, thin gate oxide of CMOS logic process constraint, and superior high endurance property with an acceptable cell size. This study proposes a brand-new cell structure and operation method to achieve the above merits with fully CMOS logic compatible technology and processes. The new logic-compatible differential self-selective program multiple-time programmable nonvolatile memory, which is using CHE program and CHH erase by controlling the voltage of SG and BL, the program/erase speed can be achieved within 2msec, and the cell also consists of 3 transistors only. Moreover, the on/off window is successfully risen up to 106 orders post 105 cycling stresses. In terms of reliability characterization, the cell has been verified to pass the criteria after 1000 hours of retention bake at 85℃, 120℃, and 150℃. Finally, the proposed new self-selective program method is able to increase the sensing window twice, to improve the reliability effectively, and to avoid the mismatch problem, further to simplify the circuit design by overhead reduction. The high performance differential-nonvolatile memory cell has been demonstrated and providing a very promising solution in logic NVM application beyond 0.18um nodes.

The self-aligned fin-shaped TFET without space between gate and source/drain is demonstrated successfully, and the fabrication process using all i-line photolithograph stepper without e-beam writer. The high ON current (> 10A) is obtained and indicates the benefit of self-alignment process. The proposed fin-shaped TFET process leads the opportunity of the advanced devices fabrication by 6-inch process with i-line photolithograph stepper.

Due to the electrical portable product, the requirements of the embedded nonvolatile memory (eNVM) are growing fast, but nowadays the eNVM can’t keep scaling down, limit by its charge retention capability. This study proposes a new differential P-channel logic-compatible multiple-time programmable non-volatile memory cell with self-recovery scheme. Its data integrity can be improved through differential structure and self-recovery scheme. The new differential P-channel logic-compatible multiple-time programmable non-volatile memory cell with self-recovery scheme is single poly and stores charge in floating gate by channel hot hole induce hot electron injection, and erases by Fowler-Nordherim tunneling. The program time is within 20ms, erase time is within 200ms, endurance is up to 100K and the cell has been verified to pass the criteria after 1000 hours of retention bake at 150oC. The self-recovery scheme can recover from the charge lose state even with significant narrowing in read window. The new cell has good operation performance and high reliability, so it will be a promising new solution for eNVM applications.

Full textSelf-incompatibility (SI) is a widespread genetic device used by flowering plants to reject their own pollen, and thus to avoid inbreeding. This cell-cell recognition mechanism is mediated by molecular interactions between gene products expressed in the pollen and those expressed in specialized cells of the pistil. The genetic determinants of the system are produced from a highly complex multigenic S-locus with multiple S-haplotypes, although other genes outside the S-locus also contribute to the phenomenon in a non-allele specific manner. SI discriminates between self and non-self pollen, as the former will be rejected (incompatible cross), whereas the latter will be allowed to accomplish fertilization (compatible cross). In the Solanaceae (to which Solanum chacoense belongs) the pistillar determinant to SI is an extremely polymorphic stylar extracellular S-RNase, whereas the pollen determinant involves the collaborative action of several members of the F-box family (SLF or S-locus F-box). This has led to the hypothesis that during compatible crosses, ubiquitin-mediated degradation of non-self S-RNases takes place (degradation model). However, it has also been found that non-self S-RNases appear to be sequestered in the vacuole during compatible crosses (sequestration model). The objective of our study was to discriminate between these two models by using immunolocalization techniques and transmission electron microscopy. We have found that the concentration of S-RNases is significantly higher in incompatible pollen tubes than in compatible ones.
