Parametrized model for obtaining electron scattering rates from radio-frequency size-effect data

A model calculation for the amplitude of radio-frequency size-effect signals as a function of temperature and sample thickness is presented. The model includes impurity scattering, electron-phonon scattering, scattering effectiveness, effective Debye temperature, energy-dependent scattering, and bulk resistance effects. By adjusting the parameters involved in the model to fit experimental data, both the impurity and electron-phonon scattering rates at the Fermi energy are obtained for an orbit on the copper Fermi surface.
