Structural Characterization of Cu Nanocrystals Formed in SiO 2 by High-Energy Ion-Beam Synthesis

Cu nanocrystals (NCs) were produced by multiple high-energy ion implantations into 5-μm -thick amorphous silica (Si O2) at liquid-nitrogen temperature. The Cu-rich Si O2 films were subsequently annealed to reduce irradiation-induced damage and promote N
