New Family of Quantum Spin Hall Insulators in Two-dimensional Transition-Metal Halide with Large Nontrivial Band Gaps
Liujiang Zhou, Liangzhi Kou, Yan Sun +6
Topological insulators (TIs) are promising for achieving dissipationless transport devices due to the robust gapless states inside the insulating bulk gap. However, currently reali…
Controllable magnetic correlation between two impurities by spin-orbit coupling in graphene
F. M. Hu, Liangzhi Kou, Thomas Frauenheim
Two magnetic impurities on the edge of a zigzag graphene nanoribbon strongly interact with each other via indirect coupling, which can be mediated by conducting carriers. By means…
Opening Band Gap without Breaking Lattice Symmetry: A New Route toward Robust Graphene-Based Nanoelectronics
Liangzhi Kou, Feiming Hu, Binghai Yan +2
Developing graphene-based nanoelectronics hinges on opening a band gap in the electronic structure of graphene, which is commonly achieved by breaking the inversion symmetry of the…
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…
