Anomalous proximity effect in an inhomogeneous disordered superconductor
arXiv:cond-mat/0403764 · doi:10.1103/PhysRevLett.93.217005
Abstract
By combining very low temperature scanning tunneling microscopy and spectroscopy on a TiN film we have observed a non uniform state comprising of superconducting (S) and normal (N) areas. The local density of states displays a spatial dependence between S and N different from the usual proximity effect. We conclude that mesoscopic fluctuations might play a major role in accordance with recent theories on superconductor-normal metal quantum transition.
