Micro-Raman spectroscopy of ultrashort laser induced microexplosion sites in silicon
L. A. Smillie, M. Niihori, L. Rapp +5
Confined microexplosions induced in silicon by powerful ultrashort laser pulses can lead to new Si phases. Some of these have not previously been observed via near-equilibrium comp…

Non-localized states and high hole mobility in amorphous germanium
Tuan T. Tran, Jennifer Wong-Leung, Lachlan A. Smillie +3
Covalent amorphous semiconductors, such as amorphous silicon (a-Si) and germanium (a-Ge), are commonly believed to have localized electronic states at the top of the valence band a…

Synthesis of strain-relaxed Ge-Sn alloys using ion implantation and pulsed laser melting
Tuan T. Tran, Quentin Hudspeth, Yining Liu +6
Ge-Sn alloys with a sufficiently high concentration of Sn is a direct bandgap group IV material. Recently, ion implantation followed by pulsed laser melting has been shown to be a…
