The high pressure phase transformation behavior of silicon nanowires
Si nanowires of 80–150 nm and 200–250 nm diameter are pressurized up to 22 GPa using a diamond anvil cell. Raman and x-ray diffraction data were collected during both compression and decompression. Electron microscopy images reveal that the nanowires retain a nanowire-like morphology (after high pressure treatment). On compression, dc-Si was observed to persist at pressures up to 19 GPa compared to 11 GPa for bulk-Si. On decompression, the metallic b-Sn phase was found to be more stable...[Show more]
