Recently, research on topological quantum materials has become a hot topic. Topological insulator, topological crystalline insulator, and Dirac half-metal are three typical topological quantum materials. In these topological materials, the electronic band structure exhibits exotic physical properties, such as massless Dirac fermion. Such unique properties may have great potential application in future electronics. For example, quantum anomalous Hall effect system, which manifests as a quantized transverse conductance in response to a longitudinally applied electric field in the absence of an external magnetic field, have immense application potential in future dissipationless quantum electronics. Based on first principle calculations, we mainly focus on exploring high-temperature quantum anomalous/spin Hall effect systems by material design and manipulation. Now, we host two national natural science foundations (NNSFC), and nearly 20 papers are published on international journals.
