Abstract Imperfections change essentially the electronic transport properties of graphene. Motivated by a recent experiment reporting on the possible application of graphene as junctions, we study transport properties in graphene-based junctions with single localized defect. We solve the Dirac–Bogoliubov–de-Gennes equation with a single localized defect superconductor–normal(graphene)–superconductor (SNS) junction. We consider the properties of tunneling conductance and Josephson current… Expand
