RADIATION DAMAGE IN THIN METAL FILMS AT 4.2°K

Abstract
The changes in electrical resistance in thin films of gold, copper, and aluminum upon irradiation with heavy charged particles were studied. As a function of dose, there is a steady increase in resistance and a monotonic decrease in the damage rate. A large part of the initial decrease is due to the size effect; however, at higher defect densities the thin film damage rate approaches bulk values.
