Materials modification has enabled significant advancements in the technological fields by allowing for precise control and manipulation of material properties. To ensure successful applications, it is crucial to have techniques that offer control over the size, shape, and morphology of the structures created. This thesis explores the use of swift heavy ions (SHI) to create nano- and microstructures on the surfaces of strontium titanate (SrTiO3) and molybdenum disulphide (MoS2) under grazing incidence geometry. The results show that SHI irradiation can induce various surface modifications, such as elongated surface defects, wave-like structures, and amorphization. This research demonstrates that by adjusting the fluence and angle of incidence of the ion beam, periodic wave-like structures can be formed on the surface of SrTiO3. These structures can be deepened to obtain more pronounced valley, which can be used to directly grow two-dimensional materials and obtain heterostructures with well-defined interfaces. The results also demonstrates that SHI irradiation can induce foldings in MoS2 samples. The angle of incidence of the ion beam and the substrate used can control the defects. The choice of substrate can also influence folds density and length. It is shown that using SrTiO3 as a substrate allows the folding with variable lengths without the need for specific crystallographic orientation conditions

L’estimation de la surface équivalente radar (SER) des fouillis de mer et terrestre est essentielle pour la conception et l’amélioration des performances des systèmes de télédétection et d’observation de la planète. Le problème particulier de la diffusion des ondes en configuration à angle rasant est de grand intérêt à cause de son importance pour la surveillance, suivi de cible, la communication et les systèmes de navigation fonctionnant au-dessus de surfaces rugueuses, terrestre ou maritime. La surface équivalente radar d’une surface rugueuse devient très faible en incidence rasante puisque la plus grande partie de la puissance incidente est diffusée dans la direction spéculaire (selon le degré de rugosité de k surface). De plus, les mécanismes principaux de diffusion sont différents aux angles rasants, par exemple, les effets de diffusion multiple (ou de diffusion d’ordre supérieur), l’ombrage, fading et les mécanismes liés au déferlement des vagues sont particulièrement présents dans une telle configuration. Par conséquent, c’est dans ce contexte que s’intègre les travaux de recherche développés dans cette thèse. Ceci en développant le modèle deux échelles à l’ordre 2 (TSM2) permettant ainsi de contribuer à l’estimation des coefficients de diffusion bistatique par les surfaces rugueuses avec l’application de ce modèle aux surfaces maritime et terrestre. L’évaluation du modèle développé est réalisée en effectuant des comparaisons par rapport aux résultats obtenus avec d’autres modèles et aussi aux données issues de la littérature ouverte

Resumo: Neste trabalho estudamos a formação e estrutura de nanopartículas (NPs) de GeSi encapsuladas em sílica, utilizando técnicas baseadas em luz síncrotron, complementadas com imagens de microscopia eletrônica de transmissão. Obtivemos a forma, o diâmetro médio e a dispersão de tamanhos usando espalhamento de raios X a baixos ângulos em incidência rasante (GISAXS). A partir dos dados de difração de raios X (XRD) foi possível obter a fase cristalina, o parâmetro de rede e o tamanho médio dos cristalitos. Estes resultados serviram como dados de entrada em um modelo para análise através da técnica de estrutura fina de absorção de raios X (EXAFS), a qual forneceu informações sobre a estrutura local na vizinhança dos átomos de Ge. Apesar dos resultados de cada uma das técnicas acima serem comumente analisados de forma separada, a combinação destas técnicas leva a uma melhor compreensão das propriedades estruturais das NPs. Através da combinação dos resultados tivemos acesso a informações tais como a deformação da rede cristalina (strain), a fração de átomos cm ambientes cristalino e amorfo, a fração de átomos de Ge diluída na matriz e a possibilidade de formação de estruturas do tipo core-shell cristalino-amorfo. Resultados adicionais como a origem do strain e a temperatura de solidificação das NPs, dentre outros, foram obtidos através de um experimento in situ de absorção de raios X em energia dispersiva (DXAS), inédito na análise deste sistema. Por fim, utilizamos as técnicas acima citadas para acompanhar a evolução dos parâmetros estruturais em amostras tratadas termicamente durante diferentes intervalos de tempo
Abstract: In this work we study the formation and structure of GeSi nanoparticles embedded in silica matrix using synchrotron-based techniques complemented by TEM images. Shape, average diameter and size dispersion were obtained from grazing incidence small angle X-ray scattering. X-ray diffraction measurements were used to obtain crystalline phase, lattice parameter and crystallite mean sizes. By using these techniques as input for extended X-ray absorption fine structure analysis, the local structure surrounding Ge atoms is investigated. Although the results for each of the methods mentioned above are usually analyzed separately, the combination of such techniques leads to an improved understanding of nanoparticle structural properties. Crucial indirect parameters that cannot be quantified by other means are accessed in our work, such as local strain, possibility of forming core-shell crystalline-amorphous structures, fraction of Ge atoms diluted in the matrix and amorphous and crystalline Ge fraction. Additional results as the origin of the strain and temperature of solidification of NPs, among others, were obtained through an in situ energy dispersive X-ray absorption experiment (DXAS), unheard in this system. Finally, we use the techniques mentioned above to monitor the evolution of the structural parameters of samples annealed during different time intervals
