Transport properties in graphene-based normal metal/insulator/pp-wave superconductor junctions

We have investigated the transport properties in the graphene-based normal metal/insulator/pp-wave superconductor junctions, in the limit of a thin barrier. It is shown that the conductance spectra and the shot noise of such system exhibit essential different features as compared to the conventional spin-triple and the graphene-based spin-singlet superconductor junctions.

Research highlights
► The potential of superconductor graphene plays an important role in conductance and shot noise.
► The conductance and shot noise can be modulated by the pair potential.
► The conductance and shot noise can be controlled by the barrier strength.
► It also offers a direct way to test the pair potential.
