Infrared properties of electron-doped cuprates: Tracking normal-state gaps and quantum critical behavior in Pr2 − xCexCuO4

We report the temperature dependence of the infrared-visible conductivity of Pr2-xCexCuO4 thin films. When varying the doping from a non-superconducting film (x = 0.11) to a superconducting overdoped film (x = 0.17), we observe, up to optimal doping (x = 0.15), a partial gap opening. The magnitude o...
