WebJun 14, 2024 · ABC trilayer graphene, as Young and his colleagues call their graphene stack, is one of the cleanest and simplest materials they could make. The second and third layers are shifted rather than twisted, each nudged over by an additional half-honeycomb, so carbon atoms below fall in the center of lattices above. WebAlthough the charge transfers from the graphene layer to MoS 2 layer, the electronic band structure seems to be a simple sum of those of each constituent when graphene stacks on top of the MoS 2 layer. And the contact properties are insensitive to the interlayer distance.
