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…

Ab-initio Study of Size and Strain Effects on the Electronic Properties of Si Nanowires
Xihong Peng, Azar Alizadeh, Sanat K. Kumar +1
We have applied density-functional theory (DFT) based calculations to investigate the size and strain effects on the electronic properties, such as band structures, energy gaps, an…
