Cold nanoindentation of germanium

Huston, Larissa; Kiran, M. S. R. N.; Smillie, L. A.; Williams, J. S.; Bradby, Jodie

Description

Diamond cubic Ge is subjected to high pressures via nanoindentation at temperatures between 45 C and 20 C. The residual impressions are studied using ex-situ Raman microspectroscopy and cross-sectional transmission electron microscopy. The deformation mechanism at 20 C is predominately via the generation of crystalline defects. However, when the temperature is lowered, the analysis of residual indentation impressions provides evidence for deformation by phase transformation and formation of...[Show more]
