In Pursuit of High Temperature Quantum Anomalous Hall State

Abstract

Major Goals: The major goal of this project is to realize the high-temperature quantum anomalous Hall (QAH) state in the topological insulator(TI)/ferromagnetic insulator (e.g. (Bi,Sb)2Te3/TIG) and TI/antiferromagnetic insulator (e.g. (Bi,Sb)2Te3/Cr2O3) heterostructures. More recently, we are also exploring the high-temperature QAH/Chern insulator states in the molecular beam epitaxy(MBE)-grown MnBi2Te4 films/heterostructures.
