Substrate effect on the electronic band structure and topological properties in a monolayer V 2 O 3 magnetic topological insulator

Year: 2025

Type: article

Abstract: Monolayer V 2 O 3 hosts a quantum anomalous Hall (QAH) state. Substrate engineering reveals that nonmagnetic h-BN preserves the QAH phase, while ferromagnetic substrates disrupt it, guiding the design of dissipationless topological electronics.
