A laser-annealing study was made of the segregation of impurities and interstitial Hg atoms in Hg0.8Cd0.2Te. The equation for the diffusion of impurities or interstitials was completed by a term which described the effect of the photon flux upon diffusion. Computer simulations of laser annealing revealed the possibility of obtaining a sharp maximum Hg concentration. This was confirmed by experiment.
