Swift heavy-ion irradiation of amorphous silicon dioxide, silicon nitride and silicon oxynitrides composite systems: from ion tracks to nanoparticle shaping
This work provides a systematic study of ion irradiation to tailor the physical and chemical properties of a-SiO2, a-Si3N4 and a-SiOxNy materials with a particular focus on three specific areas: (i) the formation of ion tracks by swift heavy-ion (SHI) irradiation in a-SiO2, a-Si3N4, and a-SiOxNy, …

Study the structural properties of Ge nanoparticles formed by ion implantation and thermal annealing in nitride-base dielectric matrices
This thesis investigates the formation of Ge nanoparticles (NPs) in amorphous Si3N4 and SiOxNy by ion implantation and thermal annealing. The structural properties of the NPs were determined using a combination of laboratory and synchrotron based techniques including cross-section transmission …
