## Description

- description: Applying long wavelength periodic potentials on quantum materials has
    recently been demonstrated to be a promising pathway for engineering novel quantum
    phases of matter. Here, we utilize twisted bilayer boron nitride (BN) as a moiré
    substrate for band structure engineering. Small-angle-twisted bilayer BN is endowed
    with periodically arranged up and down polar domains, which imprints a periodic
    electrostatic potential on a target two-dimensional (2D) material placed on top.
    As a proof of concept, we use Bernal bilayer graphene as the target material.
    The resulting modulation of the band structure appears as superlattice resistance
    peaks, tunable by varying the twist angle, and Hofstadter butterfly physics under
    a magnetic field. Additionally, we demonstrate the tunability of the moiré potential
    by altering the dielectric thickness underneath the twisted BN. Finally, we find
    that near-60°-twisted bilayer BN provides a unique platform for studying the moiré
    structural effect without the contribution from electrostatic moiré potentials.
    Tunable moiré polar substrates may serve as versatile platforms to engineer the
    electronic, optical, and mechanical properties of 2D materials and van der Waals
    heterostructures.
