Description

The critical current through superconductor-graphene-superconductor Josephson junction has been studied theoretically in terms of tunnel Hamiltonian approximation. In this paper we especially focus on the effects of vanishing density of state at Fermi level in monolayer graphene. We discuss a characteristic suppression of critical current at low temperature.
