摘要: We analyze a heat engine based on hot cavity connected via quantum wells to electronic reservoirs. discuss the output power as well efficiency both in linear and nonlinear regime. find that device delivers large of about 0.18 W/cm^2 for temperature difference 1 K nearly doubling than can be extracted from similar dots. At same time, also has good although reduced dot case. Due level spacings achieved wells, our proposal opens route towards room-temperature applications nanoscale engines.
