The lattice defects are introduced by irradiating the film with high-energy (\\simeq 6 MeV) electrons with a maximal fluence of about 2\\times 10^{17} cm^{-2}. This comparatively low dose of irradiation produces rather small radiation damage in the films. The number of displacements per atom (dpa) in the irradiated sample is about 10^{-5}. Nethertheless, this results in an appreciable increase in the film resistivity.
