Cu nanocrystals were synthesized in a thin layer of amorphous silica (SiO2) by ion implantation and thermal annealing. Subsequently the nanocrystals and a bulk Cu film standard were irradiated with high-energy Sn ions to induce structural disorder. We quantify the disorder by extended X-ray absorption fine structure (EXAFS) spectroscopy. Irradiation is found to increase the structural disorder in the nanocrystals, while the structural parameters of the irradiated film remain the same as those...[Show more]
