Diffusion of Gold in Germanium

摘要

The diffusion of Au in Ge was studied by means of the spreading-resistance method and, to a lesser extent, the radiotracer technique. It is shown to take place via the dissociative mechanism, which, even in the virtually dislocation-free Ge used in the present investigations, is Au-interstitial-controlled. Au is the only element yet found that undergoes interstitial-substitutional diffusion in Si, Ge, and their alloys.
