Engineering direct-indirect band gap transition in wurtzite GaAs nanowires through size and uniaxial strain
Andrew Copple, Nathaniel Ralston, Xihong Peng
Electronic structures of wurtzite GaAs nanowires in the [0001] direction were studied using first-principles calculations. It was found that the band gap of GaAs nanowires experien…

Engineering the work function of armchair graphene nanoribbons using strain and surface functional species: a first principles study
Xihong Peng, Fu Tang, Andrew Copple
First principles density-functional theory calculations were performed to study the effects of strain, edge passivation, and surface functional species on the structural and electr…
