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$…
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…
Stabilization Mechanism of ZnO nanoparticles by Fe doping
Jianping Xiao, Agnieszka Kuc, Thomas Frauenheim +1
Surprisingly low solubility and toxicity of Fe-doped ZnO nanoparticles is elucidated on the basis of first-principles calculations. Various ZnO surfaces that could be present in na…
