The migration of In was studied at 200 to 850C by using radiotracer techniques. It was found that the diffusivity was independent of the In concentration. Below 400C, it was also essentially independent of the temperature. At higher temperatures, the diffusivity was a function of both the temperature and of the degree of stoichiometry. When the specimen was Te-saturated, the diffusivity could be described by:

D (cm2/s) = 6.48 x 10-4 exp[-1.15(eV)/kT]

When the specimen was Cd-saturated, the diffusivity could be described by:

D (cm2/s) = 1.17 x 102 exp[-2.21(eV)/kT]
