Point-Contact spectroscopy on electron-doped Sr${}_{0.88}$La${}_{0.12}$CuO${}_2$ thin films

Abstract

We report on the spectra of point-contacts made on Sr${}_{0.88}$La${}_{0.12}$CuO${}_2$ thin films. Besides a clear evidence for the superconducting gap, we discuss the origin of specific features, such as resistance peaks at the gap voltage and the occurrence of a two-steps resistance decrease.
