摘要

In consideration of the possible point defects in Te-riched CdTe crystals, a thermodynamic equilibrium model for CdTe annealed under Te vapor was established based on the defect chemistry theory, native point defects, such as V_Cd, Cd_i, Te_i and Te_Cd were included. Point defects concentration and Fermi level were both calculated using the mass action law and quasi-chemical equations. The results systematically reveal the relationship between the point defects concentration, Fermi level, Te vapor pressure and annealing temperature. The Fermi level was pinned only when Te_Cd concentration was very large.
