论文摘要
汤森效应在电荷电流和温度梯度同时诱导热量或吸收。在这里，我们从理论上研究了由于无连接单导体中汤姆森效应诱导的热量释放/吸收而引起的温度曲线，这可能是一个简单的温度调节器。我们还对现实导体的温度曲线进行分析。结果，我们发现，对于具有较大的汤姆森系数的导体，Seebeck系数的温度导数，Thomson效应诱导的热吸收吸收使焦耳的加热超过了，从而导致散装区域的电流诱导的冷却。我们还阐明了汤姆森效应的反馈效应使系统温度稳定在热浴的一侧，这反映了汤姆森效应取决于位置并与局部温度梯度成比例的事实。这项工作将是利用汤姆森效应的热管理的基础。
The Thomson effect induces heat release or absorption under the simultaneous application of a charge current and a temperature gradient to conductors. Here, we theoretically investigate the temperature profile due to the Thomson-effect-induced heat release/absorption in junctionless single conductors which can be a simple temperature modulator. We also perform analysis of the temperature profile for realistic conductors. As a result, we find that, for a conductor with a large Thomson coefficient, the temperature derivative of the Seebeck coefficient, the Thomson-effect-induced heat absorption overcomes the Joule heating, resulting in current-induced cooling in the bulk region. We also elucidate that a feedback effect of the Thomson effect stabilizes the system temperature to one-side of the heat bath, which reflects the fact that the Thomson effect is dependent on the position and proportional to the local temperature gradient. This work will be the basis for thermal management utilizing the Thomson effect.
