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$…
Anisotropic Ripple Deformation in Phosphorene
Liangzhi Kou, Yandong Ma, Sean C. Smith +1
Two-dimensional materials tend to become crumpled according to the Mermin-Wagner theorem, and the resulting ripple deformation may significantly influence electronic properties as…
New Family of Robust 2D Topological Insulators in van der Waals Heterostructures
Liangzhi Kou, Shu-Chun Wu, Claudia Felser +3
We predict a new family of robust two-dimensional (2D) topological insulators in van der Waals heterostructures comprising graphene and chalcogenides BiTeX (X=Cl, Br and I). The la…
Phosphorene as a superior gas sensor: Selective adsorption and distinct I-V response
Liangzhi Kou, Thomas Frauenheim, Changfeng Chen
Recent reports on the fabrication of phosphorene, i.e., mono- or few-layer black phosphorus, have raised exciting prospects of an outstanding two-dimensional (2D) material that exh…
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…
