Spin thermoelectric effects in Rashba quantum dots system

Spin-dependent thermoelectric effects in Aharonov–Bohm (AB) interferometer with four Rashba quantum dots (QDs) coupled to external two one-dimensional semi-infinite metallic leads are investigated theoretically. The basic thermoelectric transport characteristics, like charge (spin) Seebeck coefficient, and the charge (spin) figure of merits, have been calculated in terms of Green's function formalism. It is found that a pure spin-up (spin-down) Seebeck coefficient can be generated by the coaction of the magnetic flux and the Rashba spin-orbit interaction (RSOI) at room temperature.
