论文摘要
我们研究了与两个储层连接的平行耦合双量子点系统的热流传输特性，该储层在库仑阻滞状态下具有温度偏差。我们证明，在该系统中存在热矫正和负差分热电导（NDTC）的影响，并分析能级差异和库仑相互作用对热整流和NDTC的影响。我们发现，当系统的不对称因子增强时，该系统可以达到高热整流比和NDTC。
We investigate the heat flow transport properties of a parallel-coupled double quantum-dot system connected to two reservoirs with a temperature bias in the Coulomb blockade regime. We demonstrate that the effects of thermal rectification and negative differential thermal conductance (NDTC) exist in this system and analyze the influences of energy level difference and Coulomb interaction on the thermal rectification and NDTC. We find that this system can achieve a high thermal rectification ratio and NDTC when the asymmetry factor of the system is enhanced.
