论文摘要
对称性,量子几何和电子相关性是凝结物质的最重要成分之一,并导致实验中的非平凡现象,例如非股本电荷转运。在这里,我们报告了固有磁性拓扑器MNBI2TE4中的非转录电荷转运。当前方向相关电阻在手性边缘上观察到,这是可磁切换,边缘位置敏感和隔层层数可控的。施加栅极电压可以有效调整非逆局电阻。对非互联电荷转运的观察和操纵表明手性在MNBI2TE4电荷运输中的基本作用,以及通过手性工程来开发范德华旋转器设备的方法。
Symmetries, quantum geometries and electronic correlations are among the most important ingredients of condensed matters, and lead to nontrivial phenomena in experiments, for example, non-reciprocal charge transport. Here we report the non-reciprocal charge transport in the intrinsic magnetic topological insulator MnBi2Te4. The current direction relevant resistance is observed at chiral edges, which is magnetically switchable, edge position sensitive and septuple layer number controllable. Applying gate voltage can effectively tune the non-reciprocal resistance. The observation and manipulation of non-reciprocal charge transport indicate the fundamental role of chirality in charge transport of MnBi2Te4, and pave ways to develop van der Waals spintronic devices by chirality engineering.
