The high pressure phase transformations of silicon and germanium at the nanoscale

Huston, Larissa

Description

Semiconducting materials are critical for the electronics industry with the two most important semiconductors being Si and Ge. Most Si and Ge has a diamond cubic (dc) structure. However, many other phases of Si and Ge that are accessible via the application of high pressure. Compression to 10-11 GPa leads to both Si and Ge phase transforming to a metallic (b-Sn) structure. On decompression, the b-Sn phase transforms into one of several metastable phases; bc8-Si, r8-Si, hd Si and Ge, and st12-Ge...[Show more]
