Prediction of Topological Crystalline Insulator and Topological Phase Transitions in Two-dimensional PbTe Films
Yi-zhen Jia, Wei-xiao Ji, Chang-wen Zhang +5
Topological phases, especially topological crystalline insulators (TCIs), have been intensively explored observed experimentally in three-dimensional (3D) materials. However, the t…
Discovery of Intrinsic Quantum Anomalous Hall Effect in Organic Mn-DCA Lattice
Ya-ping Wang, Wei-xiao Ji, Chang-wen Zhang +6
The quantum anomalous Hall (QAH) phase is a novel topological state of matter characterized by a nonzero quantized Hall conductivity without an external magnetic field. The realiza…
Two-Dimensional Arsenene Oxide: A Realistic Large-gap Quantum Spin Hall Insulator
Ya-ping Wang, Wei-xiao Ji, Chang-wen Zhang +5
Searching for two-dimensional (2D) realistic materials able to realize room-temperature quantum spin Hall (QSH) effects is currently a growing field. Here, we through ab initio cal…
Two-Dimensional Large Gap Topological Insulators with Large Rashba Spin-Orbit Coupling in Group-IV films
Shou-juan Zhang, Wei-xiao Ji, Chang-wen Zhang +2
Rashba spin orbit coupling in topological insulators has attracted much interest due to its exotic properties closely related to spintronic devices. The coexistence of nontrivial t…
