Multimechanism quantum anomalous Hall and Chern number tunable states in germanene (silicene, stanene)/$M$Bi${}_2$Te${}_4$ heterostructures

Zhe Li, Jiatong Zhang, Xiyu Hong +2

By constructing germanene (silicene, stanene)/$M$Bi${}_2$Te${}_4$ ($M$ = 3d-transition elements) heterostructures, we discovered and designed multimechanism quantum-anomalous-Hall (QAH…
