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…
Magnetic Impurity Affected by Spin-Orbit Coupling: Behavior near a Topological Phase Transition
F. M. Hu, T. O. Wehling, J. E. Gubernatis +2
We investigate the effect of spin-orbit coupling on the behavior of magnetic impurity at the edge of a zigzag graphene ribbon by means of quantum Monte Carlo simulations. A peculia…
