Samples of p-type Hg0.8Cd0.2Te, which contained dislocation densities of up to 3 x 105/cm2, low-angle grain boundaries and a few high-angle grain boundaries, were prepared. Diffusion was then monitored by using a 203Hg radiotracer and serial sectioning technique at 640K. The calculated erfc curve for diffusion in the perfect crystal corresponded to a diffusivity of 9 x 10-12cm2/s.
