Electrical Resistivity of Transition Metals. I

Abstract

The electrical resistivity of pure transition metals Mo and Nb is calculated by a realistic model. The Fermi vectors, Fermi velocities and wave functions are determined by the KKR- and APW-methods. The phonon spectrum is calculated by the Born-von Karman atomic-force-constant model. The matrix elements of the electron-phonon interaction are given by the single approximation. The results of the calculation are in reasonable agreement with experiment.
