Paper Abstract

The modulation of composition and electro-physical properties of Hg0.8Cd0.2Te by laser annealing without melting is investigated. Concentration of Hg, Cd, Te as a function of the depth from the irradiated surface, for samples with the same composition, but with different types of electrical conductivity as well as with different initial concentrations of intrinsic defects (vacation and interstitial mercury atoms) were measured before and after laser annealing. The possible explain the unexpected oscillations regularly repeated in each sample, basing upon the thermodynamic theory of decomposition of solid solution having an unbalancing thermodynamic equilibrium and basing on change the electrical properties after treatment is presented.
