Abstract
We report a tunneling study between Pr2−xCexCuO4−δ and lead as a function of doping, temperature, and magnetic field. The temperature dependence of the gap follows the BCS prediction. Our data fit a nonmonotonic d-wave order parameter for the whole doping range studied. From our data we are able to conclude that the electron-doped cuprate Pr2−xCexCuO4−δ is a weak-coupling BCS dirty superconductor.
