The dependence of the diffusivity upon the Hg vapour pressure and the temperature was determined by using tracer techniques. It was found that the solubility in Hg0.8Cd0.2Te was governed by neutral atoms, and that the diffusivity was determined by charged atoms of the dopant. The results:

undoped:     D (cm2/s) = 1.6 x 10-7 exp[-0.63(eV)/kT]

Ag-doped:     D (cm2/s) = 1.6 x 10-8 exp[-0.60(eV)/kT]

In-doped:     D (cm2/s) = 1.1 x 10-8 exp[-0.64(eV)/kT]

were explained in terms of a dissociative mechanism.
