Quantum spin Hall states in graphene interacting with WS or WSe
T. P. Kaloni, L. Kou, T. Frauenheim +1
In the framework of first-principles calculations, we investigate the structural and electronic properties of graphene in contact with as well as sandwiched between WS and WSe$…

Graphene-based topological insulator with an intrinsic bulk band gap above room temperature
Liangzhi Kou, Binghai Yan, Feiming Hu +5
Topological insulators (TIs) represent a new quantum state of matter characterized by robust gapless states inside the insulating bulk gap. The metallic edge states of a two-dimens…

Proximity Enhanced Quantum Spin Hall State in Graphene
Liangzhi Kou, Feiming Hu, Binghai Yan +4
Graphene is the first model system of two-dimensional topological insulator (TI), also known as quantum spin Hall (QSH) insulator. The QSH effect in graphene, however, has eluded d…
