This work reports the correlation of changes in structural and optical properties of a-SiNx:H thin films irradiated with 100 MeV Au8+ at various fluences. Cross-sectional TEM studies show the evolution of discontinuous ion tracks with a radius of 3 n

The irradiation of sub-stoichiometric amorphous hydrogenated Silicon nitride (a-SiNx:H) films with 100 MeV Ni7+ ions leads to a loss of hydrogen from these films and results in a compacted and denser films. It has been found that in addition to hydro

Hydrogen loss from a-SiNx:H films under irradiation with 100 MeV Ag7+ ions using elastic recoil detection analysis (ERDA) experiments is reported. The results are explained under the basic assumptions of the molecular recombination model. The ERDA hy

Near surface silver nanoparticles embedded in silicon oxide were obtained by 40 keV silver negative ion implantation without the requirement of an annealing step. Ion beam induced local heating within the film leads to an exodiffusion of the silver i
