Abstract
The theoretically-predicted anisotropic nature of the indentation phase transformation in silicon (Si) is observed directly in experiments using hyperspectral, confocal Raman microscopy. The anisotropy is reflected in the two-dimensional distribution of the residual diamond cubic phase and high-pressure phases in indented Si(001), Si(110), and Si(111) surfaces, and is linked to the number and orientation of the {111} slip systems of the diamond cubic phase that are activated during indentation.Citation
