近场热晶体管

Near-field thermal transistor

Philippe Ben-Abdallah, Svend-Age Biehs

摘要:

使用一块三个分离的固体元素,热源和漏极与栅极由绝缘体金属过渡材料交换近场热辐射,我们介绍了一个纳米级模拟的场效应晶体管,它能够控制两个机构之间的倏逝热光子交换的热量的流动。通过在其临界值附近改变栅极温度,可以通过栅极上的微小动作可逆地切换、放大和调制热主体(源极)和冷主体(漏极)之间交换的热通量。这样的设备可以在纳米级热管理领域中找到重要的应用,并且它开辟了关于旨在使用光子电流而不是电流进行信息处理的非接触式热电路的发展的新前景。

英文摘要:

Using a block of three separated solid elements, a thermal source and drain together with a gate made of an insulator-metal transition material exchanging near-field thermal radiation, we introduce a nanoscale analog of a field-effect transistor which is able to control the flow of heat exchanged by evanescent thermal photons between two bodies. By changing the gate temperature around its critical value, the heat flux exchanged between the hot body (source) and the cold body (drain) can be reversibly switched, amplified, and modulated by a tiny action on the gate. Such a device could find important applications in the domain of nanoscale thermal management and it opens up new perspectives concerning the development of contactless thermal circuits intended for information processing using the photon current rather than the electric current.
