论文摘要
我们研究具有有效的电子电子相互作用的量子点的线性和非线性热电电压，以及弱，能量依赖性的隧道偶联到电子接触。值得注意的是，我们发现热电电压显示了可以合理化的排斥相互作用的特征。这些热电电压特性在非线性方案中与巨大潜力和温度差异非常强大，我们期望这可以在当前的最新实验中证明。此外，在非线性操作下，我们发现，效率的大型产生区域的扩展区域在Curzon-Ahlborn绑定的效率下仅被特征尖锐的倾角中断。
We study the linear and nonlinear thermovoltage of a quantum dot with effective attractive electron-electron interaction and weak, energy-dependent tunnel-coupling to electronic contacts. Remarkably, we find that the thermovoltage shows signatures of repulsive interaction which can be rationalized. These thermovoltage characteristics are robust against large potential and temperature differences well into the nonlinear regime, which we expect can be demonstrated in current state-of-the-art experiments. Furthermore, under nonlinear operation, we find extended regions of large power production at efficiencies on the order of the Curzon-Ahlborn bound interrupted only by a characteristic sharp dip.
