Abstract
Most studies on the effect of the magnetic field (B-field) on the transport property of graphene have assumed the low-energy approximation represented by the linear Dirac Hamiltonian. Here, we apply the non-equilibrium Green´s function (NEGF) method based on the tight-binding model to analyze the transport characteristic of graphene heterojunctions in the presence of B-field. The NEGF approach also allows us to analyze the transport under biased condition, which pertains to most practical devices.
