## Description

- description: The stacking order and twist angle provide abundant opportunities for
    engineering band structures of two-dimensional materials, including the formation
    of moiré bands, flat bands, and topologically nontrivial bands. The inversion
    symmetry breaking in rhombohedral-stacked transitional metal dichalcogenides (TMDCs)
    endows them with an interfacial ferroelectricity associated with an out-of-plane
    electric polarization. By utilizing twist angle as a knob to construct rhombohedral-stacked
    TMDCs, antiferroelectric domain networks with alternating out-of-plane polarization
    can be generated. Here, we demonstrate that such spatially periodic ferroelectric
    polarizations in parallel-stacked twisted WSe2 can imprint their moiré potential
    onto a remote bilayer graphene. This remote moiré potential gives rise to pronounced
    satellite resistance peaks besides the charge-neutrality point in graphene, which
    are tunable by the twist angle of WSe2. Our observations of ferroelectric hysteresis
    at finite displacement fields suggest the moiré is delivered by a long-range electrostatic
    potential. The constructed superlattices by moiré ferroelectricity represent a
    highly flexible approach, as they involve the separation of the moiré construction
    layer from the electronic transport layer. This remote moiré is identified as
    a weak potential and can coexist with conventional moiré. Our results offer a
    comprehensive strategy for engineering band structures and properties of two-dimensional
    materials by utilizing moiré ferroelectricity.
