Interfacing Quantum Spin Hall and Quantum Anomalous Hall insulators: Bi
bilayer on MnBi$_2$Te$_4$-family materials
Meeting of non-trivial topology with magnetism results in novel phases of matter, such as Quantum Anomalous Hall (QAH) or axion insulator phases. Even more exotic states with high and tunable Chern numbers are expected at the contact of intrinsic magnetic topological insulators (IMTIs) and 2D topological insulators (TIs).Here we synthesize …
