摘要	The thermoelectric effect in a quantum dot structure is theoretically studied with the application of circularly polarized light. We find that at low temperature, the polarized light induces the antiresonant transport of spin-up electron through this structure, leading to the significant contribution of the spin-up electron to the thermoelectric effect. Alternatively, at high temperature, the opposite results come into being, i.e., the transport of the spin-down electron plays a dominant role in driving the thermoelectric effect. Thus, apparent thermospin effect occurs in this structure, which is strongly dependent on temperature. In addition, it shows that the thermoelectric effect is efficiently enhanced and the thermospin effect is further manipulated by the presence of electron interaction.
