Multiple negative differential conductance regions and inelastic phonon assisted tunneling in graphene-hBN-graphene structures
In this paper we study in detail the effect of the rotational alignment between a hexagonal boron nitride (hBN) slab and the graphene layers in the vertical current of a a graphene-hBN-graphene device. We show how for small rotational angles, the transference of momentum by the hBN crystal lattice le...
