The Au was diffused into n-type crystals, which contained nuclei for point defects, at 1150C. Hexagonal stacking faults were induced by the Au diffusion. Some of these specimens were heat-treated again at 1000C by continuous annealing. The size and density of the stacking faults depended upon the substitutional Au concentration, and could be controlled by the Au diffusion. During in-diffusion, the size and areal density of the faults were proportional to the square root of the Au concentration. During annealing, the areal and volume densities of the faults were proportional to the Au concentration. The size during annealing, and the volume density during in-diffusion, were independent of the Au diffusion.
