Abstract
Low-dimensional magnetic topological insulators exhibiting the quantum anomalous Hall (QAH) effect have garnered significant interest among researchers. Ta2Se3, a novel two-dimensional (2D) monolayer (ML) material, has been predicted to be a QAH insulator, characterized by a high Curie temperature of 474 K, a large topological band gap of 157 meV and an intriguing spin-oriented Chern number by first-principles calculations. Furthermore, the layer Hall effect (LHE) has been observed in bilayer antiferromagnetic Ta2Se3 under a vertical electric field. These outstanding tunable topological properties indicate very bright prospects for two-dimensional Ta2Se3 in topological physical devices at high temperatures.
