Abstract : The films studied in the experiment were produced by vaporizing CdSe in vacuum on a glass base or on the bottom of a Diuar container with the help of electrodes. The study pertained to the effect of oxygen, hydrogen, nitrogen and air sorption on the electrical conductivity of CdSe layers. It was determined that oxygen has the greatest effect on changes in the electrical conductivity of CdSe layers. The specific resistance, changes in electrical conductivity, as well as changes in relative photo-sensitivity in the air depend on the thickness of the layer. Production conditions and the thickness of the film also determine the constant k. It was also shown that at low temperature, activating energy is lower in a vacuum than in oxygen, while pure nitrogen has no effect on it. (Author)
