N2 - The tunneling spectra of the electron-doped cuprate Pr2-x Cex CuO4-δ as a function of doping and temperature are reported. We find that the superconducting gap, Δ, shows a BCS-type temperature dependence even for extremely low carrier concentrations. Moreover, Δ follows the doping dependence of Tc, in strong contrast with tunneling studies of the hole-doped cuprates. From our results we conclude that there is a single superconducting energy scale in the electron-doped cuprates.
