AI 中文摘要
纳米级热电器件可将微量热量转化为电能，但如果外部条件及由此产生的温差无法预先知晓，会出现什么情况？我们提出一种反馈机制，用于优化基于量子点接触（QPC）的热机性能。量子点探测器可测量外部条件，并对QPC的特性给出自主反馈。我们预计，该反馈机制对于外部条件未知的稳态热机，以及使动态充电过程适应电势积累，具有实验应用价值。
英文摘要
Nanoscale thermoelectric devices convert tiny amounts of heat into power. But what happens if the external conditions and resulting temperature differences are not a priori known? We propose a feedback mechanism that optimizes the performance of a quantum-point-contact-based heat engine (QPC). A quantum-dot detector measures the external conditions and gives autonomous feedback on the QPC's properties. We expect this feedback mechanism to be experimentally relevant for steady-state engines with unknown external conditions and for adapting dynamic charging processes to the potential buildup.
