Structural characterization of pressure-induced amorphous silicon

Haberl, Bianca; Liu, A. C. Y.; Bradby, Jodie; Ruffell, Simon; Williams, James; Munroe, Paul

Description

We investigate the structure and mechanical properties of pressure-induced (PI) amorphous silicon (a-Si) and compare this to the more extensively characterized case of a-Si created by ion implantation. To study the effect of thermal history we also examine the structure of both PI and ion-implanted a-Si after a low-temperature "relaxation" anneal (450°C). Indentation testing suggests that structural changes are induced by thermal annealing. As-prepared forms of a-Si deform via plastic flow,...[Show more]
