Long-range moire tuning effect via inter-layer drag interaction.

ABSTRACT: Constructing moiré superlattices has been demonstrated to be a powerful approach for tailoring the electronic properties of two-dimensional van der Waals materials. However, the periodic moiré potential diminishes rapidly away from the interface between the two stacked layers, restricting the moiré modulation only at the superlattice interface. Here, we present an alternative strategy to extend the influence range of the moiré tuning through drag interaction, a dynamic process involving inter-layer momentum/energy transfer mediated by Coulomb scatterings. By fabricating a unique electronic double-layer structure comprising a graphene moiré superlattice and a pristine graphene layer, we observe several intriguing inter-layer drag behaviors dominated by moiré physics. Notably, measuring the
