Microscopic theory of the proximity effect in superconductor-graphene nanostructures
We present a theoretical analysis of the proximity effect at a graphene-superconductor interface. We use a tight-binding model for the electronic states in this system, which allows us to describe the interface at the microscopic level. Two different interface models are proposed: one in which the superconductor induces a finite …
