Edge effects on the electronic properties of phosphorene nanoribbons
Xihong Peng, Qun Wei, Andrew Copple
Two dimensional few-layer black phosphorus crystal structures have recently fabricated and demonstrated great potential in applications of electronics. In this work, we employed fi…
Strain engineered direct-indirect band gap transition and its mechanism in 2D phosphorene
Xihong Peng, Andrew Copple, Qun Wei
Recently fabricated two dimensional (2D) phosphorene crystal structures have demonstrated great potential in applications of electronics. In this work, strain effect on the electro…
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…
