ANDREEV REFLECTION MODULATED THERMOELECTRIC TRANSPORT IN A THREE TERMINAL QUANTUM DOT

　The influence of spin-polarized electronic transports associated with Andreev reflection on the thermoelectric currents is investigated in a three-terminal hybridized system, consisting of an interacting quantum dot tunnel coupled to one superconducting, one ferromagnetic, and one normal lead. The numerical results show that the competition between the Andreev reflection and normal tunneling leads to the changes in the magnitude and direction of both thermal charge current and thermal spin current. Experimentally, it can be realized by modulating the gate voltage and the coupling strength between the superconducting lead and quantum dot.
