摘要：

The contrast obtained after long thermal annealing in high purity ZnTe, by SEM in the cathodoluminescence mode and by TEM is investigated. The contrast variations are due to segregation or extraction of residual impurities (LiZn, CuZn, AgZn) which control the electrical and optical properties of the ZnTe. These studies allow to approach the self‐compensation problem in terms of limited solubilities of impurities, function of stoichiometry and temperature, the acceptor reserve being in the defects (inclusions, grain, and subgrain boundaries).
