Abstract

Diamond-hexagonal (dh) Ge has been produced by Vickers micro-indentation of a Ge single crystal and investigated by high resolution transmission electron microscopy (HREM). The results are consistent with the mechanisms that have been proposed earlier for the generation of dh Si. The hexagonal phase of these elemental semiconductors may be produced by two related mechanisms: (a) secondary twinning or (b) the intersection of two twins. The hexagonal germanium produced by both of these mechanisms has been observed and is presented in the present paper.
