Abstract
The change of the electrical resistivity and of the thermoelectric power caused by vacancies in copper and gold was calculated. The effective scattering cross-section and its dependence on the energy of electrons was calculated in the free-electron approximation using the partial wave method. The scattering potential associated with a vacancy was approximated by a square barrier or by a screened Coulomb potential. The experimental value of the electrical resistivity is in good agreement with the value calculated in the free-electron approximation but the thermoelectric power differs appreciably from the free-electron value. Using an experimentally determined term, which depends on the shape of the Fermi surface, agreement with experiment was obtained.
