The Au concentration was measured as a function of the dislocation density, which was introduced by various deformation processes in float-zone or Czochralski material, in order to check a theory of Au diffusion which involved a self-interstitial sink efficiency coefficient. In this way, the value of the coefficient could be determined. It was noted that the value of the coefficient was very sensitive to the nature of the dislocations which were involved and to the O concentration. On the other hand, transmission electron microscopic observations showed that the dislocations were sinks for self-interstitials.
