## Description

- description: Heterostructures of two-dimensional (2D) materials comprise clean van
    der Waals (vdW) interfaces that can facilitate charge or energy transfer. Recently,
    the 2D ferroelectric ­ CuInP2S6 (CIPS) has been integrated with graphene and other
    2D materials to realize potentially novel low energy electronic devices. However,
    the influence of 2D CIPS on the properties of graphene and doping across the vdW
    interface has not been studied in detail. Here, we study graphene field effect
    transistors (FETs) with CIPS as the top gate. We find that CIPS leads to modulation
    of the graphene Fermi level due to local doping. We also find polarization-induced
    hysteresis in CIPS-gated graphene FETs. Electrical transport measurements from
    50 to300 K show that above 200 K, the ferroelectric response decreases. As a result,
    the hysteresis voltage windows in the graphene ferroelectric FETs (FeFET) transfer
    curves decrease above 200 K. Our results show that interfacial remote doping affects
    the macroscopic polarization and performance of CIPS-based graphene FeFETs.
