Abstract
The relaxation-time dependence of the driving force in electromigration is calculated from an expression derived by Schaich using a density-matrix analysis in the relaxation-time approximation. The result does not support Lodder's conjecture on the dependence of the force on the relaxation time. It is shown that Lodder's conjecture is based upon a subtle error which he made in evaluating a response function in the limit of large relaxation time. Recent experimental results for hydrogen electromigration in disordered transition-metal alloys are discussed in the light of existing theory, and it is concluded that additional effects need to be incorporated into the theory in order to explain these experiments.
