文摘

We use of the Green's function method and the tight-binding Hamiltonian model. Using DFT methods we will parametrize the tight-binding hopping and on-site energies. The electronic properties of graphene/h-BN and h-BN bilayers system are studied. The electron transport in the GNR/BNNR/GNR structure can open a conduction gap.
