Abstract

A large increase in photoconductivity, the temperature quenching effect, and the appearance of the photovoltaic effect have been observed in thermally treated CdTe in the air up to 450 °C. It has been shown that the introduction of the level Ec - 0.60 eV, associated with the cadmium vacancy, is responsible for the enhancement of photosensitivity. Experiments have confirmed that the photovoltage arises due to the inhomogeneities in the distribution of defects in the bulk. Some characteristics of the dynamic behaviour of the photo-emf are also discussed.
