Dual-gated hBN/bilayer-graphene superlattices and the transitions between the insulating phases at the charge neutrality point

We report on transport properties in dual-gated hexagonal boron nitride (hBN)/bilayer-graphene (BLG) superlattices. Here, BLG is nontwisted, i.e., plain. This paper focuses the charge neutrality point (CNP) for a plain BLG. Under perpendicular magnetic field, transitions between two insulating phases at CNP are detected by varying displacement field with study resistance-temperature characteristics and magnetoresistance. work opens avenues exploring global phase diagram of hBN/BLG superlattices beyond CNP.
