Abstract:
For elements with low atomic number, or shallow absorption edges falling in the energy range below ~1 keV, x-ray absorption studies are often limited by surface sensitivity and the necessity of a vacuum environment, making bulk-sensitive measurements and for example studies of liquids difficult. An exciting alternative is provided by X-ray Raman scattering (XRS) spectroscopy. It is used to measure a photon-in-photon-out process, where a hard x-ray photon loses only part of its energy creating an excitation of an inner core electron. As such, it is the x-ray analogue of electron energy loss spectroscopy. The advantage of XRS is that the incident photon energy can be chosen freely and thus low-energy absorption edges can be studied with high-energy X-rays. Thus XRS is becoming increasingly popular since it allows for bulk-sensitive measurements of inner core spectra where the corresponding x-ray absorption threshold falls into the soft x-ray regime. This lifts all constraints on the sample environment inherent to soft x-ray studies, and offers access to bulk-sensitive information on solids, liquids and gases as well as systems in enclosed sample environments such as high-pressure cells. For example the microscopic structure of water within the supercritical regime has been recently studied using the oxygen K-edge excitation spectra measured by XRS, yielding new information on the hydrogen-bond network of water in extreme conditions [1]. Another important feature of XRS is that it allows for other than dipole transitions to be studied, thanks to an practically unlimited range of momentum transfer offered by hard x-rays. These higher order multipole excitations can yield novel information on the electronic structure, not accessible by many other spectroscopies [2]. The availability of XRS instruments at third-generation synchrotron radiation sources has made highly accurate XRS measurements possible. XRS can be even used as a contrast mechanism in three-dimensional X-ray imaging [3]. In this contribution, the capabilities of XRS and recent examples of novel studies allowed by it will be reviewed.

Abstract:
An end-station for X-ray Raman scattering spectroscopy at beamline ID20 of the European Synchrotron Radiation Facility is described. This end-station is dedicated to the study of shallow core electronic excitations using non-resonant inelastic X-ray scattering. The spectrometer has 72 spherically bent analyzer crystals arranged in six modular groups of 12 analyzer crystals each for a combined maximum flexibility and large solid angle of detection. Each of the six analyzer modules houses one pixelated area detector allowing for X-ray Raman scattering based imaging and efficient separation of the desired signal from the sample and spurious scattering from the often used complicated sample environments. This new end-station provides an unprecedented instrument for X-ray Raman scattering, which is a spectroscopic tool of great interest for the study of low-energy X-ray absorption spectra in materials under in situ conditions, such as in operando batteries and fuel cells, in situ catalytic reactions, and extreme pressure and temperature conditions.

Abstract:
An experimental system for polarized soft X-ray Raman scattering spectroscopy has been constructed. The soft X-ray spectrometer is based on the Rowland circle geometry with a holographic spherical grating. Three types of gratings are used to cover the energy range from 18 eV to 1200 eV. According to a ray-trace simulation, the resolution is expected to be 200 meV at 700 eV by using a 10 µm slit width. The polarized and depolarized soft X-ray Raman scattering spectra can be measured by rotating the soft X-ray spectrometer around the axis of the incident beam. Preliminary measurements of polarized and depolarized spectra were accomplished at undulator beamline BL-2C of the Photon Factory.

Abstract:
The present thesis is devoted to theoretical studies of resonant X-ray scattering and propagation of strong X-ray pulses. In the first part of the thesis the nuclear dynamics of different molecules is studied using resonant X-ray Raman and resonant Auger scattering techniques. We show that the shortening of the scattering duration by the detuning results in a purification of the Raman spectra from overtones and soft vibrational modes. The simulations are in a good agreement with measurements, performed at the MAX-II and the Swiss Light Source with vibrational resolution. We explain why the scattering to the ground state nicely displays the vibrational structure of liquid acetone in contrast to excited final state. Theory of resonant X-ray scattering by liquids is developed. We show that, contrary to aqueous acetone, the environmental broadening in pure liquid acetone is twice smaller than the broadening by soft vibrational modes significantly populated at room temperature. Similar to acetone, the "elastic" band of X-ray Raman spectra of molecular oxygen is strongly affected by the Thomson scattering. The Raman spectrum demonstrates spatial quantum beats caused by two interfering wave packets with different momenta as the oxygen atoms separate. It is found that the vibrational scattering anisotropy caused by the interference of the "inelastic" Thomson and resonant scattering channels in O2. A new spin selection rule is established in inelastic X-ray Raman spectra of O2. It is shown that the breakdown of the symmetry selection rule based on the parity of the core hole, as the core hole and excited electron swap parity. Multimode calculations explain the two thresholds of formation of the resonant Auger spectra of the ethene molecule by the double-edge structure of absorption spectrum caused by the out-of- and in-plane modes. We predict the rotational Doppler effect and related broadening of X-ray photoelectron and resonant Auger spectra, which has the same magnitude as its counterpart-the translational Doppler effect. The second part of the thesis explores the interaction of the medium with strong X-ray free-electron laser (XFEL) fields. We perform simulations of nonlinear propagation of femtosecond XFEL pulses in atomic vapors by solving coupled Maxwell's and density matrix equations. We show that self-seeded stimulated X-ray Raman scattering strongly influences the temporal and spectral structure of the XFEL pulse. The generation of Stokes and four-wave mixing fields starts from the seed field created during pulse propagation due to the formation of extensive ringing pattern with long spectral tail. We demonstrate a compression into the attosecond region and a slowdown of the XFEL pulse up to two orders of magnitude. In the course of pulse propagation, the Auger yield is strongly suppressed due to the competitive channel of stimulated emission. We predict a strong X-ray fluorescence from the two-core-hole states of Ne created in the course of the two-photon X-ray absorption.

Abstract:
The object of this thesis is the study of nanostructured thin films using inelastic fight scattering and elastic x-ray scattering techniques. Their use in combination with other techniques is a powerful tool for the investigation of nanostructured materials. X-ray, Raman and Brillouin characterisation of cluster-assembled carbon films, promising for applications in the field of catalysis, hydrogen storage and field emission, is here presented. X-ray reflectivity (XRR) provided a measure of the density. Raman spectroscopy showed that the local bonding in these amorphous films depends on the size distribution of the clusters and that it is possible to select the cluster size in order to grow films with tailored properties. Brillouin scattering provided a characterisation at the mesoscopic scale and an estimate of the elastic constants, revealing a very soft material. XRR was employed to study density, layering and roughness of a wide range of amorphous carbon films grown with different techniques. Some films possess an internal layering due to plasma instabilities in the deposition apparatus. By comparing XRR with Electron Energy Loss Spectroscopy, a unique value for the electron "effective mass" was deduced and a general relationship between sp(^3)-content and density was found. XRR and H effusion were used to determine the hydrogen content. A study of the size-dependent melting temperature in tin nanoparticle thin films was undertaken with a combined use of X-Ray Diffraction (XRD) and light scattering. A redshift in the position of a Rayleigh peak in the temperature-dependent Brillouin measurements was shown to be related to the melting of the nanoparticles and explained by an effective medium model. XRD also provided information on the low-level of stress in the particles. Low-frequency Raman scattering was used to study the behaviour of the acoustic modes of a single particle as a function of temperature.

Resumo: O uso da região de espalhamento na espectrometria de raios-X (XRS, do inglês, X-Ray Spectrometry) aliada à quimiometria é uma aplicação recente que tem mostrado bons resultados na discriminação de amostras orgânicas. Nesse trabalho, a proposta de se utilizar XRS para solucionar um problema de classificação taxonômica de Lantana sp, utilizando-se folhas desse vegetal não foi alcançada devido à reconhecida evolução contínua desta espécie. No entanto, o estudo de espécies do gênero Musa e das famílias Polemoniaceae, Asteraceae e Portulacaceae, utilizando-se pseudofrutos e sementes, respectivamente foi bem sucedido. A análise de componentes principais (PCA) realizada com os espectros obtidos da irradiação dos pseudofrutos e das sementes mostrou boa correlação entre a disposição das amostras e a classificação nos níveis gênero, espécies e variedades. Variáveis que poderiam justificar a discriminação obtida desses vegetais foram estudadas como exemplo o estudo envolvendo a utilização de carboidratos. Foram realizadas: a regressão de sacarose, frutose e glicose em solução aquosa e frutose e glicose em suco, com bons coeficientes de linearidade (0,998; 0,995; 0,998; 0,994 e 0,991, respectivamente); a discriminação de carboidratos; a regressão do índice de doçura e a rotação específica da luz polarizada de carboidratos; e a regressão da inversão da sacarose. Além da discriminação dos vegetais e do estudo de carboidratos, esse trabalho também apresenta a fundamentação teórica para explicar o surgimento desta técnica e um provável potencial que ela poderá apresenta para o futuro
Abstract: The use of scattering on X-ray Spectrometry (XRS) allied to chemometrics is a new application that is showing good results in discrimination of organics. In the present work the proposal of applying XRS to solve the taxonomic classification of Lantana sp species, using leafs of these plants was not reached due to the evolution process this plant is still undergoing. Nevertheless, this motivated a discrimination study of species of Musa genus (banana) and species of Polemoniaceae, Portulacaceae and Asteraceae families, using fruits and seeds, respectively. Principal component analysis of spectra of fruits and seeds show good correlation between sample arrangement and taxonomic classification in genus, species and varieties. Looking for variables that could justify the discriminations obtained, studies were developed involving carbohydrates. It was realized: sucrose, fructose and glucose regression in aqueous solutions and fructose and glucose calibration in juice solutions with good linear coefficients (0.998; 0.995; 0.998; 0.994 e 0.991, respectively); carbohydrates discrimination; X-ray spectra correlation with sweetness degrees and specific rotation of polarized light of carbohydrates; and regression of kinetics of sucrose inversion. Besides the vegetable classifications and the carbohydrate studies, this work presents a theorical basis to explain the XRS characteristics, the history before the arising of this method and its potentialities for the future

Abstract:
Ce travail de thèse porte sur les spectroscopies d’électrons de niveau de cœur ainsi que leur modélisation par la suite de code open source Quantum ESPRESSO. Il porte en particulier sur la Spectroscopie d’Absorption des rayons X (XAS), déjà bien établie, et la Spectroscopie Raman des rayons X (XRS), une alternative au XAS gagnant en popularité, par exemple dans le cas de mesures sous conditions extrêmes. Le premier objectif de cette thèse était l’étude de l’impact des vibrations thermiques des noyaux sur les contributions multipolaires en XAS et en XRS. En effet, le modèle QHA utilisé pour prendre en compte ces effets a déjà fait ses preuves dans le cas d’oxides légers, mais n’a jamais été utilisé pour étudier ces effets sur les canaux quadripolaire en XAS et monopolaire en XRS. L’étude repose sur la comparaison entre calcul et expérience, sur deux composés de référence : TiO2 rutile et α-Al2O3. Par ailleurs, un défaut du modèle QHA concernant la reproduction de subtils effets de dépendance angulaires a été découvert et corrigé par la théorie des groupes. Le second objectif de cette thèse était l’implémentation du calcul des seuils L2,3 en XRS dans le module XSpectra de Quantum ESPRESSO. Cette implémentation est inspirée des précédentes implémentations du calcul de seuils K en XRS et de seuils L2,3 en XAS. L'implémentation comprend les contribution monopolaire et dipolaire jusqu’au premier ordre du développement de l’opérateur de transition XRS. Elle est testée par comparaison entre calcul et expérience pour divers composés du soufre. Un bon accord entre calcul et expérience est obtenu, bien que très sensible à l’approximation du trou de cœur choisie
This thesis work focuses on core level spectroscopies and their modelling by Quantum ESPRESSO, an open-source suite of codes. In particular this work focuses on X-Ray absorption spectroscopy (XAS), already well established, and X-Ray Raman Scattering (XRS), proving to be an increasingly popular alternative to XAS, for example under harsh experimental conditions. The first objective of this work was to study the impact of the thermal vibrations of nuclei on the multipole contributions available in XAS and XRS. Indeed, the QHA model used in this work to account for these vibration effects has been used to study light oxides before, but never to assess these effects on the secondary contribution channels of XAS (quadrupole) and XRS (monopole). The study relies on comparison between calculation and experimental data on two well-known reference compounds, rutile TiO2 and α-Al2O3. Moreover, a flaw of the QHA model when trying to reproduce subtle angular dependence signals was discovered and corrected using group theory. The second objective of the thesis was to implement calculation of XRS L2,3 edges in the XSpectra module of Quantum ESPRESSO. It was inspired by the previous implementations of XAS L2,3 edges and XRS K edges calculations in XSpectra. The monopole and dipole contributions were implemented up to the first order of the expansion of the XRS transition operator. It was tested by comparing calculation and measured data on various sulphur compounds. Good agreement with data could be produced, but was found very sensitive to the chosen core hole approximation

Resumo: Silício amorfo hidrogenado (a-Si:H) é um material amplamente usado na indústria microeletrônica. Ele é normalmente preparado a partir da decomposição do silano (SiH4). A diluição do silano em hidrogênio (H2) resulta em a-Si:H com propriedades eletrônicas superiores devido ao ataque químico preferencial às ligações mal-formadas. Níveis elevados de diluição resultam na formação de silício microcristalino (µc-Si). O objetivo deste trabalho é estudar o ordenamento da vizinhança química do silício através da transição a-Si:H ® µc-Si por espectroscopia de absorção de raios-X (XAS). Como a maior parte da desordem em a-Si:H manifesta-se na forma de variações nos ângulos de ligação, é necessário estudar o regime de espalhamento múltiplo (XANES), que corresponde às primeiras dezenas de energia (eV) acima da borda de absorção. Filmes finos de silício próximo à transição amorfo-microcristalino foram preparadas por HWCVD a partir de SiH4 diluido em H2. Nas condições utilizadas, a nucleação de µc-Si ocorre a partir de uma espessura crítica de aproximadamente 100 nm. Depositando-se amostras em forma de cunha é possível obter uma superfície de a-Si:H de um lado da amostra e de µc-Si do outro. Também foram investigadas amostras preparadas por PECVD em condições próximas à formação de pó no reator (chamadas de silício polimorfo, ou seja, entre amorfo e policristalino). Em princípio elas poderiam ter uma estrutura local mais ordenada
Abstract: Hydrogenated amorphous silicon (a-Si:H) is a material very used in the microelectronics industry. It is usually prepared starting from the decomposition of the silane (SiH4). Hydrogen dilution of the silane source gas is used to grow a-Si:H with superior electronics properties due to the preferential chemical attack to the bad formed bonding. High hydrogen levels induce the growth of microcrystalline silicon (µc-Si). The objective this work is study the order of the chemical neighborhood of the silicon through the transition a-Si:H ® µc-Si for x-ray-absorption Spectroscopy (XAS). As most of the disorder in the a-Si:H shows in the form of bonding angles variation, it is necessary to study the multiple scattering regime (XANES), that corresponds to the first dozens of energy (eV) above the absorption edge. Thin silicon films close the transition amorphous-microcrystalline was prepared for hot-wire chemical vapor deposition (HWCVD). For these conditions, the nucleation of the µc-Si oc-curs at a critical thickness of approximately 100 nm. Deposited the samples in the wedge form, it is possible to get a-Si:H surface in the one side and µc-Si in the other side. Also prepared samples were investigated for PECVD in close conditions to the powder formation in the reactor (calls of silicon polymorphous, a silicon sample between amorphous and polycrystalline) with the local order structure

Abstract:
AbstractIn this chapter, we will thoroughly discuss characterization techniques used to elucidate the exact structure and define properties of peptide-based nanomaterials. In particular we divide methods into: Quality control performance (mass spectroscopy and high-performance liquid chromatography. Spectroscopy (Fourier transform infrared spectroscopy, Raman spectroscopy, circular and linear dichroism, nuclear magnetic resonance and fluorescence spectroscopy). Microscopy (scanning and transmission electron microscopies, atomic force microscopy, optical and polarized light microscopy). Scattering (small angle X-ray and neutron scattering, X-ray diffraction). Bulk structures (mainly hydrogels) rheological characterization. The methodology is described for molecular structures, self-assembled nanostructures and aggregates, as well as hybrid, composite and/or conjugated nanomaterials and their bulk forms. Both common, as well as more exotic versions of all methods are presented in the context of peptide-based nanomaterials. Where utilized, examples of combinatorial use of techniques are demonstrated. Representative studies accompany the discussion and usefulness of all presented methods.

Abstract In Chapter 2 we utilized the basic relation between the double differential scattering cross-section and excitations in the scattering system, as given in equation (2.3) only by considering excitations of the valence electron systems of condensed matter. We will now examine inelastic scattering processes connected with excitations of core-electrons from closed shells into unoccupied states about which we want to learn by this type of spectroscopy. In this case we will speak, for more historical reasons, of non-resonant X-ray Raman scattering or spectroscopy, or still more briefly of X-ray Raman scattering or spectroscopy (XRS), if mixing up with resonant X-ray Raman scattering is not to be suspected.

Abstract When Sparks jr. (1974), still using conventional X-ray sources, started to investigate resonant emission of X-rays, and Eisenberger et al. (1976a,b), using for the first time synchrotron radiation for inelastic X-ray scattering studies, detected the so-called Raman shift and the anomalous width of the resonant emission, nobody would believe that it was just RIXS, which became the most important field of inelastic X-ray scattering, at least for investigating actual materials of high practical importance.

Abstract:
Abstract Small-angle scattering is defined by the fact that the intensity of a radiation scattered by a target varies strongly over a few angular degrees in the vicinity of the incident direction. According to A. Guinier, this forward scattering was observed for the first time in 1934 by C.V. Raman, in an experiment of X-ray scattering by carbon black. It has since been observed that colloidal substances and polymers in solution also scatter X-rays in the forward direction (this is called central scattering); moreover, it appeared that the width of the central peak is inversely proportional to the size of the scattering objects.

Abstract:
The electronic structure of molecules includes electronic (2-10 eV, UV-Vis absorption), vibrational (10-2 - 2 eV, infrared spectroscopy & Raman scattering), and rotational (10–5 – 10–3 eV, microwave spectroscopy) energy levels that are probed by appropriate spectroscopy methods. Light, incident on a molecule or molecular solid, is either absorbed (IR, single photon, non-zero derivative of dipole moment), or elastically (Rayleigh) or inelastically (Raman, two-photon, non-zero derivative of the polarizability) scattered. Fourier transform infrared (FTIR) spectroscopy finds much use in materials characterization, including in studying the curing of polymer composites now incorporated in aircraft structures. When atoms form solids their electronic structure, particularly the energy levels of the outer electrons involved in the bonding, are significantly altered. Both occupied and unoccupied levels in solids are probed. Photoemission spectroscopy (PES) with X-rays (XPS) or ultraviolet light (UPS) incidence, and inverse PES probe occupied and unoccupied energy levels of surfaces, respectively. X-ray absorption spectroscopy (XAS) complements XPS, and probes unoccupied energy levels of solids. X-ray absorption near-edge structure (XANES) provides information on the final density of unoccupied states, the transition probabilities, and many body effects. Extended X-ray absorption fine structure (EXAFS) provides element-specific nearest neighbor distances and their coordination number.

Abstract:
Phonons are introduced as an example of quasi-particles that can only exist in matter. Debye’s quantum model for heat capacity of solids and comparison with experimentin different temperature ranges is presented. The dispersion relations of lattice vibration (phonons) and quantization for chains of atoms presented, revealing the optical and acoustic modes; anharmonic effects are discussed. Crystal lattice structures and Brillouin zones are introduced. Phonon scattering and the Umklapp process described. The variation of the thermal conductivity of dielectrics with temperature is interpreted. X-ray scattering studies of phonon dispersion relations are described. Coupling between phonons with photons in polaritons is explained: Raman scattering studies of GaN used to exhibit the cross-over of their dispersion relations. The Mössbauer effect, a recoilless process, and its dependence on temperature are explained.

Abstract:
One of the outstanding uncertainties in modelling x-ray laser experiments lies in determining the actual plasma parameters which crucially affect the prediction of laser performance. Electron temperatures are commonly inferred experimentally from x-ray emission spectra or from the Landau damping cutoff of stimulated Raman scattering, neither of which directly measures the temperature with sufficient precision at the location where lasing occurs.

Abstract:
Multiple higher-order Stokes of stimulated rotational Raman scattering (SRRS) in compressed hydrogen covered the wavelength range from ~1078 nm to ~1355 nm using ~1.2 ps pump pulses from a Yb:YAG laser. The use of a supercontinuum seed, as well as circular polarization of pump pulses at high hydrogen pressure, made it possible to significantly reduce the threshold for SRRS and suppress vibrational Stokes modes. Cascade excitation of SRRS, corresponding to a shift of 587 cm-1, ensured a spectrum spanning four Stokes orders and a conversion efficiency of 52% with an output energy exceeding 3 mJ. The synthesized spectrum corresponded to ~14 fs transform-limited pulses.
