Nanoindentation-induced phase transformation in relaxed and unrelaxed ion-implanted amorphous germanium
We have investigated nanoindentation-induced plastic deformation in amorphousgermanium (a-Ge) prepared by high-energy self-ion implantation. Using cross-sectional transmission electron microscopy, micro-Raman spectroscopy, and force-displacement curve analysis, we find strong evidence for a pressure-induced metallic phase transformation during indentation. Crystalline diamond-cubic Ge-I is observed in residual indents. Relaxed and unrelaxed structural states of a-Ge exhibit similar behavior on...[Show more]
