Self-Assembled Ge QDs Formed by High Temperature Annealing on GaAs and AlxGa1-xAs (001)
William A. O'Brien, Meng Qi, Lifan Yan +5
This work studies the spontaneous self-assembly of Ge QDs on AlAs, GaAs, and AlGaAs by high temperature in-situ annealing in molecular beam epitaxy (MBE). The morphology of Ge dots…

Band Anticrossing in Dilute Germanium Carbides Using Hybrid Functionals
Chad A. Stephenson, William A. O'Brien, Meng Qi +3
Dilute germanium carbides (Ge1-xCx) offer a direct bandgap for compact silicon photonics, but widely varying results have been reported. This work uses ab initio simulations with H…
