In the present work, we theoretically study thermoelectric transport and heat transfer in a junction including a double quantum dot in a serial configuration coupled to nonferromagnetic electrodes. We focus on the electron transport within the Coulomb blockade regime in the limit of strong intradot interactions between electrons. It is shown that under these conditions, characteristics of thermoelectric transport in such systems strongly depend on electron occupation on the dots and on interdot Coulomb interactions. We demonstrate that these factors may lead to a heat current rectification and analyze potentialities of a double-dot in a serial configuration as a heat diod.
在本工作中，我们从理论上研究了一个包含串联配置的双量子点并与非铁磁电极耦合的结中的热电输运和热传递。我们关注电子在库仑阻塞区域内、电子间强点内相互作用极限下的输运。结果表明，在这些条件下，此类系统中热电输运的特性强烈依赖于量子点上的电子占据情况以及点间库仑相互作用。我们证明这些因素可能导致热电流整流，并分析了串联配置的双量子点作为热二极管的潜力。
