## Description

- description: We review the fabrication and transport characterization of hexagonal
    boron nitride (hBN)/Bernal bilayer graphene (BLG) moiré superlattices. Due to
    the moiré effect, the hBN/BLG moiré superlattices exhibit an energy gap at the
    charge neutrality point (CNP) even in the absence of a perpendicular electric
    field. In BLG, the application of a perpendicular electric field tunes the energy
    gap at the CNP, which contrasts with single-layer graphene and is similar to the
    family of rhombohedral multilayer graphene. The hBN/BLG moiré superlattice is
    associated with non-trivial energy-band topology and a narrow energy band featuring
    a van Hove singularity. By employing a dual-gated device structure where both
    the perpendicular displacement field and the carrier density are individually
    controllable, systematic engineering of the energy-band structure can be achieved.
    The data presented here demonstrate the universality and diversity in the physics
    of hBN/BLG moiré superlattices.
