Summary of "Matrix-material dependence on the elongation of embedded gold nanoparticles induced by 4 MeV C60 and 200 MeV Xe Ion irradiation."

We report the elongation of embedded Au nanoparticles (NPs) in three different matrices, i.e., amorphous carbon (a-C), indium tin oxide (InSnO; ITO) crystal and calcium fluoride (CaF) crystal, under irradiations of 4 MeV Ccluster ions and 200 MeV Xe ions. Under 4 MeV Ccluster irradiation, strong sputtering is induced in CaFlayer so that whole the layer was completely lost at a fluence of 5 × 10ions/cm. Even though, Au NPs were partly observed in the SiO, probably due to the recoil implantation. Amorphous carbon (a-C) layer exhibits low sputtering loss even under 4 MeV Cirradiation. However, the elongation in a-C layer was low. While ITO layer shows certain decrease in thickness under 4 MeV Cirradiation, large elongation of Au NPs was observed under both 4 MeV Cand 200 MeV Xe irradiation. The ITO layer preserved the crystallinity even after the large elongation was induced. This is the first report of the elongation of metal NPs in a crystalline matrix.
