摘要：
In the paper, we describe a single-level quantum dot with an external magnetic field that works as a nano-thermoelectric refrigerator. Based on the model, the expressions for the cooling rate (R), the power input (P) and the coefficient of performance (epsilon) are derived. The effects of the magnetic field strength and the level energy on the performance of the refrigerator are revealed. The optimal performance characteristics of the refrigerator are analyzed by numerical calculation. Furthermore, the practical operating regions of the cycle are determined.
