Stability, Electronic and Magnetic properties of magnetically doped topological insulators Bi2Se3, Bi2Te3 and Sb2Te3
Jian-Min Zhang, Wenmei Ming, Zhigao Huang +5
Magnetic interaction with the gapless surface states in topological insulator (TI) has been predicted to give rise to a few exotic quantum phenomena. However, the effective magneti…
Majorana Fermions on Zigzag Edge of Monolayer Transition Metal Dichalcogenides
Rui-Lin Chu, Gui-Bin Liu, Wang Yao +3
Majorana fermions, quantum particles with non-Abelian exchange statistics, are not only of fundamental importance, but also building blocks for fault-tolerant quantum computation.…
Three-band tight-binding model for monolayers of group-VIB transition metal dichalcogenides
Gui-Bin Liu, Wen-Yu Shan, Yugui Yao +2
We present a three-band tight-binding (TB) model for describing the low-energy physics in monolayers of group-VIB transition metal dichalcogenides (=Mo, W; =S, Se, Te)…
Magnetoelectric effects and valley controlled spin quantum gates in transition metal dichalcogenide bilayers
Zhirui Gong, Gui-Bin Liu, Hongyi Yu +4
In monolayer group-VI transition metal dichalcogenides (TMDC), charge carriers have spin and valley degrees of freedom, both associated with magnetic moments. On the other hand, th…
