Electrical switching of Chern insulators in moire rhombohedral heptalayer graphene
Zhiyu Wang, Qianling Liu, Xiangyan Han +14
In orbital Chern insulators, the chemical potential acts as a tuning knob to reverse chirality in dissipationless edge currents, enabling electric-field control of magnetic order-k…

Unveiling the origin of unconventional moire ferroelectricity
Ruirui Niu, Zhuoxian Li, Xiangyan Han +13
Interfacial ferroelectricity emerges in heterostructures consisting of nonpolar van der Waals (vdW) layers, greatly expanding the scope of two dimensional ferroelectrics. In partic…
