Abstract
We study the associated effects of polarized light and temperature bias on the charge and spin transport through a semiconductor quantum dot connected to two ferromagnetic electrodes. A spin-dependent thermoelectric current is generated in such a system, and a totally pure spin current can be obtained without an accompanying charge current. Furthermore, the sign reversal of tunnel magnetoresistance is found, which is induced by temperature difference and Rabi frequency.
