Four-electron Negative-U Vacancy Defects in Antimony Selenide
Xinwei Wang, Sean R. Kavanagh, David O. Scanlon +1
The phenomenon of negative-U behavior, where a defect traps a second charge carrier more strongly than the first, has been established in many host crystals. Here we report the cas…

Band Versus Polaron: Charge Transport in Antimony Chalcogenides
Xinwei Wang, Alex M. Ganose, Seán R. Kavanagh +1
Antimony sulfide (Sb2S3) and selenide (Sb2Se3) are emerging earth-abundant absorbers for photovoltaic applications. Solar cell performance depends strongly on charge carrier transp…

Nonvolatile ferroelectric control of topological states in 2D heterostructures
Hua Bai, Xinwei Wang, Weikang Wu +4
Quantum spin Hall (QSH) insulator materials feature topologically protected edge states that can drastically reduce dissipation and are useful for the next-generation electronics.…
