We predict an enormous order-dependent quantum enhancement of thermoelectric effects in the vicinity of higher-order interferences in the transmission spectrum of a nanoscale junction. Single-molecule junctions based on 3,3'-biphenyl and polyphenyl ether (PPE) are investigated in detail. The nonequilibrium thermodynamic efficiency and power output of a thermoelectric heat engine based on a 1,3-benzene junction are calculated using many-body theory and compared to the predictions of the figure-of-merit ZT.
我们预测在纳米结的传输谱中高阶干涉附近,热电器件的热效应会出现巨大的与序参量相关的增强。我们详细研究了基于联苯和聚醚(PPE)的单分子结。利用多体理论计算了基于 1,3-苯环结的热电器件的非平衡热力学效率和功率输出,并与优值 ZT 的预测进行了比较。
