Araujo, Leandro; Giulian, Raquel; Sprouster, David; Schnohr, Claudia; Llewellyn, David; Kluth, Patrick; Ridgway, Mark C; Cookson, D J; Foran, Garry J


A combination of conventional and synchrotron-based techniques has been used to characterize the size-dependent structural and thermal properties of Ge nanocrystals (NCs) embedded in a silica (a-SiO2) matrix. Ge NC size distributions with four different diameters ranging from 4.0 to 9.0 nm were produced by ion implantation and thermal annealing as characterized with small-angle x-ray scattering and transmission electron microscopy. The NCs were well represented by the superposition of bulklike...[Show more]
