Using different types of WSe2 and graphene-based heterostructures, we experimentally determine the offset between the graphene … Web1 day ago · This value corresponds to the graphene charge neutrality point (CNP), where n = 0. The CNP is reached at a finite V G = 12 V, due to an unintentional doping of the graphene during the fabrication process. The positive (negative) value of V G − V Dirac corresponds to electron (hole) injection.
