▎ 摘　　要

We study the transport properties of a gapped graphene-based normal metal/insulator/p-wave superconductor junction in the limit of a thin barrier. In this work, we aim to study the influence of three types of p-wave superconductivity in tunneling conductance spectra for p(x), p(y) and p(x) + ip(y)-pairing symmetry. In particular, the normal conductance is obtained in terms of the bias voltage, eV, the energy gap of graphene, mv(F)(2), and also the insulator electrostatic potential, V-0, taking realizable experimental data for physical parameters in structure. It is shown that the conductance versus bias voltage for p(x)-symmetry taking into account the superconductor electrostatic potential, U-0, exhibits a similar feature as for p(x) + p(y)-symmetry. We see that, the step functional behavior of charge carriers depends on the type of p-pair coupling, as similar behavior has been observed in d-wave superconductivity in the same structure.
