Abstract
Annealing ZnTe in Zinc vapour at 400-550 °C gives two effects : within the bulk of the samples, impurities (copper and lithium) are released from the Te excess and act as CuZn and LiZn. On the surface, an electrically compensated zone is created. The result of these effects is the appearance of an acceptor bump located below the surface exposed to a short time anneal under zinc pressureKeywords
