The effect of dielectric coating on the superconductivity of aluminum films

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

We report measurements on the changes of the superconducting transition temperatureT c and the normal resistanceR n of quench condensed aluminum films during dielectric coating. N2 and noble gas coatings result in an exponential change of the superconducting properties due to the modification of the phonon spectrum. O2 and Se coatings result in a nonmonotonic change ofT c andR n due to charge transfer processes and resonance scattering of the electrons into localized states within the coating layers.
