摘要:

我们表明,通过正常的金属-绝缘体-超导体隧道结的电流传输的高温环境的影响,可以描述的超导体中的有效态密度(DOS)。在电阻低欧姆环境的限制下,该DOS简化为众所周知的Dynes形式。我们的理论结果是支持在工程环境中的实验。我们应用我们的研究结果,以提高性能的单电子旋转栅门,一个潜在的候选人,一个可编程的电流源。

英文摘要:

We show that the effect of a high-temperature environment in current transport through a normal metal-insulator-superconductor tunnel junction can be described by an effective density of states (DOS) in the superconductor. In the limit of a resistive low-ohmic environment, this DOS reduces into the well-known Dynes form. Our theoretical result is supported by experiments in engineered environments. We apply our findings to improve the performance of a single-electron turnstile, a potential candidate for a metrological current source.
