“…It is found that the AR process is tunable by an electric field due to the buckled structure of silicene [8]. The influence of exchange field on the subgap transport in a silicene-based NM-SC junction has been also investigated [9][10][11][12][13][14]. Zhou et al found that it is possible to generate a 0 − π phase transition in a silicene-based Josephson junction by applying an off-resonant circularly polarized field in silicene [15].…”

We theoretically investigate the spin-polarized subgap transport and valley-triplet pairing states in a silicene-superconductor junction. By using the nonequilibrium Green's function, it is found that the subgap conductance is strongly affected by the spin polarization induced by an off-resonant circularly polarized light. More importantly, the presence of valley-mixing scattering at the interface could result in a valley-triplet Andreev reflection (AR) process, where the incident electrons and reflected holes come from the same valley. We also find that the amplitude of the valley-triplet AR is controllable by tuning the intensity of the light, the position of the Fermi level, and even the interface coupling strength. Particularly, the fully valley-polarized conductance spectrum shows distinctive behaviors, which is beneficial for us to verify and detect the possible valley-triplet pairing states as well as the spin/valley polarizations in silicene. Our results may pave the way for the applications of silicene in spin-valleytronics.

“…On the other hand, the AR process in silicene-based superconducting junctions showed that incident electrons with up (down) spin in the K valley are always reflected as holes with down (up) spin in the K ′ valley at the interface [8][9][10][11][12][13][14].…”
