摘要:

非晶绝缘氧化铟薄膜的输运性质的测量已被解释为存在的超导岛的绝缘侧的无序调谐的超导体-绝缘体转变的证据。虽然薄膜不是颗粒状的,但其行为类似于在颗粒状薄膜中观察到的行为。结果支持的理论模型中,超导性的破坏无序产生空间非均匀配对的光谱间隙。

英文摘要:

Measurements of transport properties of amorphous insulating indium oxide thin films have been interpreted as evidence of the presence of superconducting islands on the insulating side of a disorder-tuned superconductor-insulator transition. Although the films are not granular, the behavior is similar to that observed in granular films. The results support theoretical models in which the destruction of superconductivity by disorder produces spatially inhomogenous pairing with a spectral gap.
