Miniaturization of micro- and opto-electronics devices has led to the development of nanotechnologies. At this scale, the density of interfaces drastically increases explaining their critical role in the device performances. In this thesis, interest has been focused on interactions at the interfaces between heterogeneous materials during their first growth stages by molecular beam epitaxy. Each chapter studies a specific interface with the objective of monolithically integrating III-V semiconductors (GaAs) on silicon substrate, which is a main goal of the INL’s Heteroepitaxy and Nanostructures team. Two complementary approaches have been considered: GaAs nanowires on Si (111) substrate and the research of a Zintl phase as a buffer layer ade...
