  Motivated by the recent observations of possible p-wave superconductivity in
the bismuth-nickel (Bi/Ni) bilayer, we explore theoretically the possibilities
of realizing p-wave superconductivity in this bilayer. We begin with a
literature survey on this system and related materials which have similar
superconducting transition temperature. From the survey, the superconducting
mechanism in this bilayer system is suggested to be phonon mediated type II
superconductivity. A simple model is proposed to explain why the p-wave like
Andreev reflection signals are likely to be observed in the surface probe,
assuming the strong spin-orbit coupled surface state of Bi thin film is not
completely destroyed by the formation of alloys.
