Annealing at two different temperatures of 950 °C and 650 °C yielded two different nanocrystal size distributions with an average diameter of 8.1 and 2.5 nm, respeKeywords: Annealing; Copper; Crystal atomic structure; Ion implantation; Metallic films; Silica; X ray scattering; Bulk elemental metals; Nanocrystals; Small angle X-ray scattering (SAXS); X-ray absorption fine structure (EXAFS) spectroscopy; Nanostructured materia EXAFS; Ion implantation; Nanocrystals; SAXS200610.1016/j.nimb.2006.04.1122015-12-08
