The diffusivity in Hg0.8Cd0.2Te was studied by using tracer and sectioning techniques at 230 to 401C, under various Hg partial pressures. When In vapour sources were used, the diffusivity was independent of the In content and Hg pressure and the results could be described by:

D (cm2/s) = 8.20 x 10-2 exp[-1.36(eV)/kT]
