We theoretically demonstrate that the heat flows can be manipulated by designing a three-terminal quantum-dot system consisting of three Coulomb-coupled quantum dots connected to respective reservoirs. In this structure, the electron transport between the quantum dots is forbidden, but the heat transport is allowed by the Coulomb interaction to transmit heat between the reservoirs with a temperature difference. We show that such a system is capable of performing thermal management operations, such as heat flow swap, thermal switch, and heat path selector. An important thermal rectifier, i.e., a thermal diode, can be implemented separately in two different paths. The asymmetric configuration of a quantum-dot system is a necessary condition for thermal management operations in practical applications. These results should have important implications in providing the design principle for quantum-dot thermal management devices and may open up potential applications for the thermal management of quantum-dot sys...

三端量子点热管理器件

我们从理论上证明，可以通过设计一个三端量子点系统来操纵热流，该系统由连接到各自储层的三个库仑耦合量子点组成。在这种结构中，量子点之间的电子传输被禁止，但通过库仑相互作用允许热传输，以在具有温差的储层之间传输热量。我们展示了这样的系统能够执行热管理操作，例如热流交换、热开关和热路径选择器。一个重要的热整流器，即热二极管，可以在两个不同的路径中单独实现。量子点系统的非对称配置是实际应用中热管理操作的必要条件。
