Abstract

A diffusion model for the calculation of the charge transport caused by moving dislocations in simple ionic crystals is developed. The model is based on the assumption that the charge transport originates from the diffusional motion of vacancies under the influence of the potential field of moving dislocations. The numerical results obtained for LiF and NaCl doped with divalent cation impurities show that the assumed mechanism is suitable for the explanation of the main features of the experimental results.
