Abstract
Equations are proposed for quasi-chemical reactions leading to the formation of intrinsic and impurity defects and defect complexes in Cl-doped cadmium telluride crystals during annealing in cadmium vapor at different temperatures. The equilibrium constants for the formation of (Cl +Te V 2−Cd )− defect complexes and Te 2+Cd antisite defects are calculated. An analytical expression is derived for the cadmium partial pressure corresponding to a type conversion. The conditions are established for producing n- and p-type CdTe〈 Cl〉 crystals with controlled carrier concentration.
