Pure thermal spin current and perfect spin-filtering with negative differential thermoelectric resistance induced by proximity effect in graphene/silicene junctions

This paper aims to investigate the spin dependent transport properties in hybrid nanoribbons, using non equilibrium Greens function method. The effects of temperature gradient between left and right leads, ferromagnetic exchange field, local external electric fields are also included. results show that up down currents produced flow opposite directions with almost equal magnitudes. evidently shows carrier is dominated by thermal current. Whereas electron current disappeared.
