Interaction of the ZnxCd1-xTe and Cd0,2Hg0,8Te solid solutions with NaNО2–НІ–lactic acid etchants

The chemical dissolution of CdTe and ZnxCd1-xTe (х = 0,04; 0,1) and Cd0,2Hg0,8Te solid solutions single crystals in the NaNO2–HI–lactic acid etchant compositions has been investigated. Concentration and kinetic dependences of the etching rates have been constructed. It was shown that the quality of the treatment by iodine emerging etchants improved at the increasing of zinc and mercury contents in the solid solutions. The etchant compositions and modes of the chemical dynamic polishing of the mention above single crystals have been optimized.
