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