Bismuthylene Monolayer: A Promising Quantum Spin Hall Insulator with Large Band Gaps
Run-wu Zhang, Chang-wen Zhang, Wei-xiao Ji +2
By means of first-principles calculations, we predict a new 2D QSH insulator in the porous allotrope of Bismuth monolayer, bismuthylene, its dynamics stability being confirmed by p…
Two-Dimensional Group-IV Chalcogenide Si2Te2 film: A New Quantum Spin Hall Insulator with Sizable Band Gap
Run-wu Zhang, Wei-xiao Ji, Chang-wen Zhang +2
Quantum spin Hall (QSH) effect is promising for achieving dissipationless transport devices due to the robust gapless states inside insulating bulk gap. Here, by using first-princi…
Robust Room-Temperature Quantum Spin Hall Effect in Methyl-functionalized InBi honeycomb film
Sheng-shi Li, Wei-xiao Ji, Chang-wen Zhang +2
Two-dimensional (2D) group-III-V honeycomb films have attracted significant interest for their potential application in fields of quantum computing and nanoeletronics. Searching fo…
Large-gap quantum spin Hall state in functionalized dumbbell stanene
Ya-ping Wang, Wei-xiao Ji, Chang-wen Zhang +5
Two-dimensional dumbbell (DB) stanene has been proposed as a promising candidate material for realizing quantum spin Hall effect (QSHE) by Tang et al [P. Tang, P. Chen, W. Cao, H.…
