摘要：
A spin-dependent Seebeck diode is theoretically proposed, which consists of the junction with a semiconductor quantum dot sandwiched between the ferromagnetic and nonmagnetic leads. It is shown that both thermoelectric and thermal-spin currents driven by temperature bias exhibit asymmetric I-C(S)- Delta T characteristics. In the Coulomb blockade regime, anomalous suppression of the thermoelectric (thermal-spin) current is observed at the forward thermal bias direction (Delta T > 0). This asymmetry in the current profile suggests a diode-like behavior with respect to temperature bias. More inte...
