摘要: 离Tc不太远时,隧道注入准粒子,使Sn膜进入非平衡状态,注入到一定强度时,非平衡超导膜上出现电压,这种电压类似于N-S界面电阻,越靠近Tc越大,但相应的电阻值比N-S界面电阻大几个数量级,并且注入增强到一定程度时,电阻值会突然减小,甚至消失。

Abstract: Superconducting Sn films are driven into the non-equililbrium state by tunnel injection of quasi-particles. The voltage across the films starts to appear when injection current increase to a certain value. Near the transition temperature of the Sn films, Tc, the corresponding resistance increase rapidly with increasing temprature. The behavior is similar to the resistance of the normal-superconductor interface. But, the observed effect is orders of magnitude larger than N-S interface resistance and the value of resistance will decrease suddenly, even vanish, when the injection current increases to a higher threshold value I".
