Abstract

These experiments were undertaken to determine more precisely the minimum energy Td needed to displace an atom from its lattice position. The resistivity increase as a function of integrated flux was measured at various electron energies. The damage-production curve, thus obtained, was the sum of two components. The first contribution is due to direct displacement processes. From a projection of this component to zero, we estimate TdCu=16–19 eV and TdAu=33–36 eV. The second contribution, the subthreshold events, are due to various ``soft spots'' associated with unavoidable impurities in the nominally 99.999% pure copper and gold specimens. It has been shown that displacements near dislocations do not contribute in a significant manner. It has been further shown that the formation of light-atom interstitials can contribute to subthreshold processes. While this does not conclusively prove that subthreshold processes in nominally pure copper and gold are due to the presence of light-atom impurities, we believe this to be the most probable subthreshold mechanism.
