Based on nanoelectronic devices that can act as power generators or refrigerators, the relations between the entropy production rate and the thermal efficiency or coefficient of performance are obtained for two types of electron filters. It is found that the decrease of the entropy production rate does not always guarantee the increase of the thermal efficiency or coefficient of performance, indicating that the state of the minimum entropy production rate does not correspond to that of the maximum thermal efficiency or coefficient of performance in these electronic devices. It implies the fact that different from the thermal efficiency or coefficient of performance, the entropy production rate is not a good objective function for optimizing the performance of electronic devices. However, entropy analyses will be helpful to deeply understanding the thermodynamic properties of electronic devices. These results obtained her e will provide a feasible scheme to further optimize and improve the performances of electronic devices.

基于可以用作发电机或电冰箱的纳米电子器件，对于两种类型的电子滤波器，获得了熵生产率与热效率或性能系数之间的关系。发现熵产生率的降低并不总是保证热效率或性能系数的增加，这表明最小熵产生率的状态与最大热效率或性能系数的状态不对应。在这些电子设备中。这表明，与热效率或性能系数不同，熵产生率并不是优化电子设备性能的良好目标函数。然而，熵分析将有助于深入了解电子设备的热力学性质。她的这些结果将为进一步优化和改善电子设备的性能提供可行的方案。
