The rate of decomposition of a solid solution of Au in n-type Si with a dislocation density of 104/cm2 was studied. The Au concentration was determined by means of Hall effect and resistivity measurements. At 500 to 700C, the diffusivity could be described by:

D (cm2/s) = 1.0 x 100 exp[-1.57(eV)/kT]
