Silicon crystallite formation in ion-implanted quartz

Abstract
Rapid thermally annealed silicon-implanted x-cut α-quartz samples have been examined by Rutherford backscattering and Raman microprobe spectroscopy. The data indicate that the silicon has diffused at 1200 °C to form a buried layer of crystallites of size 1–10 μm. The crystallites are preferentially oriented and under substantial stress.
