Asymmetric quantum Hall effect and diminished $\hat{I}½=0$ longitudinal resistance in graphene/InSe heterostructures

Wenxue He, Shijin Li, Jinhao Cheng +9

We investigate quantum transport in graphene/InSe heterostructures and find major asymmetries in the longitudinal resistance ($R_{xx}$) and vanishing $R_{xx}$ peaks at high magneti…
