The following works are base on the study of self assembly structures at the nanometric scale. At this scale the surface energy have a major impact in this organization. For a better understanding of this mechanism we studied different Silicon-Germanium base structures. We experimentally studied the crystalline or amorphous growth on different types of substrates (amorphous: SiO2, crystalline: Si or SOI). Some of these substrates were nano-structured using a focused ion beam using gallium source or gold-silicon source. In addition, we were able to use different surfaces such as TiO2 or porous silicon to study the organization of the material small size pore(less than 50nm).Les travaux présentés dans ce manuscrit, sont basés sur l'étude de l...
