Abstract

We present a study on inelastic thermoelectric devices, wherein charge currents and electronic and phononic heat currents are intricately interconnected. The employment of double quantum dots in conjunction with a phonon reservoir positions them as promising candidates for quantum thermoelectric diodes and transistors. We illustrate that quantum coherence yields significant charge and Seebeck rectification effects. It is worth noting that, while the thermal transistor effect is observable in the linear response regime, especially when phonon-assisted inelastic processes dominate the transport, quantum coherence does not enhance thermal amplification. Our work may provide valuable insights for the optimization of inelastic thermoelectric devices.
量子相干对非弹性热电器件的影响:从二极管到晶体管
我们介绍了一项关于非弹性热电设备的研究,其中电荷电流与电子和声子热流错综复杂地相互关联。双量子点与声子库的结合使用,使它们成为量子热电二极管和晶体管的理想候选器件。我们说明,量子相干性产生了显著的电荷和塞贝克整流效应。值得注意的是,虽然在线性响应机制中可以观察到热晶体管效应,尤其是在声子辅助非弹性过程主导传输的情况下,但量子相干性并不会增强热放大效应。我们的工作可能会为非弹性热电设备的优化提供有价值的见解。
