Supercurrent in superconducting graphene
Published 7 Jan 2010 in cond-mat.supr-con and cond-mat.mes-hall | (1001.1048v1)
Abstract: The problem of supercurrent in superconducting graphene is revisited and the supercurrent is calculated within the mean-field model employing the two-component wave functions on a honeycomb lattice with pairing between different valleys in the Brillouin zone. We show that the supercurrent within the linear approximation in the order-parameter-phase gradient is always finite even if the doping level is exactly zero.
