论文摘要
近年来，在近场政权中运行的热设备有许多建议，这些设备利用了相转移材料。在这里，我们介绍了将近场热二极管和晶体管结合使用超导材料与正常（非耐药性）金属的理论研究。确切地说，我们表明，由NB和AU制成的两个平行板形成的系统可以表现出前所未有的整流比，在NB超导临界温度周围的温度下非常接近统一，并且对于近场状态内的较大间隙尺寸值。此外，我们还表明，放置在Au板之间的超导型NB层可以作为近场热晶体管的作用，其中可以通过不同的不同参数（例如NB层的温度和厚度）或NB层和NB层之间的距离和AU板之间的距离来极大地调节放大因子。总体而言，我们的工作表明了使用超导体用于实现近场热设备的潜力。
In recent years there has been a number of proposals of thermal devices operating in the near-field regime that make use of phase-transition materials. Here, we present a theoretical study of near-field thermal diodes and transistors that combine superconducting materials with normal (non-superconducting) metals. To be precise, we show that a system formed by two parallel plates made of Nb and Au can exhibit unprecedented rectification ratios very close to unity at temperatures around Nb superconducting critical temperature and for a wide range of gap size values within the near-field regime. Moreover, we also show that a superconducting Nb layer placed between Au plates can operate as a near-field thermal transistor where the amplification factor can be greatly tuned by varying different parameters such as the temperature and thickness of the Nb layer or the distance between the Nb layer and the Au plates. Overall, our work shows the potential of the use of superconductors for the realization of near-field thermal devices.
