Investigation of quantum transport and local density of states in a graphene strip connected to a square lattice

Abstract: We theoretically express quantum transport at Dirac points via graphene quantum billiard as a non-magnetic material to connect metallic leads. Our results indicate that the quantum billiard of graphene is similar to a resonant tunneling device. The centerpiece size and the Fermi energy of the graphene quantum billiard play an important role in resonant tunneling. In graphene, a change of carrier density can affect plasmon polaritons. At the Dirac point, the conductivity of graphene depends on the geometry, so … Show more
