▎ 摘　　要

We theoretically study graphene-based ferromagnet/insulator/p-wave superconductor hybrid structure, where an anomalous zero bias conductance peak (ZBCP) is exhibited. With the exchange field h increased, the zero-bias conductance dips (ZBCDs) for both the p(x) and p(y)-wave situations develop into ZBCPs at h/E-F > 1, which are just contrary to the situation at h/E-F, < 1. Furthermore, with the enhancement of barrier strength chi, the conversion from the ZBCD to ZBCP is displayed in the region of h/E-F >1 for the p(x)-wave, whereas the sharp ZBCP remains all the time at any h for the p(y)-wave. More interestingly, the zero-bias conductance for the p(x)-wave keeps unchanged upon increasing x, while for the p(y)-wave, exhibits periodical modulation of chi. The singular features can be used to not only identify the p-wave superconductivity and spin polarization in graphene but also pave the way to a new class of tunable superconducting spintronic devices based on large-scale graphene.
