Serial sectioning and radiotracer techniques were used to study the diffusion of 115mCd in single crystals of Hg0.8Cd0.2Te in the absence or presence of an electric

field. It was found that the tracer diffusion data at 200 to 400C could be described by:

D (cm2/s) = 8.8 x 10-9 exp[-0.52(eV)/kT]

In an electric field of 0.6V/cm, at 120 to 140C, the diffusivity on the cathode or anode side was 6.0 x 10-13cm2/s:
