INVESTIGATION OF SOME ELECTROPHYSICAL PROPERTIES OF SEMICONDUCTOR VIDEO INFORMATION STORAGE BASED ON SELENIUM AND LEAD OXIDE

The results of a study of the physicochemical characteristics of glassy and crystalline semiconductors and semiconductor materials based on PbO-Se are presented. It is shown that for the efficient operation of vacuumless photovoltaic converters (PVCs) with memory, information storage devices are required, consisting of a highly sensitive recording layer and a high-resistance storage layer. According to the data of theoretical scientific and applied research, effective operation of this type of PVC with memory requires creating multilayer inorganic video information storage devices with a continuous structure. In our case, the lead (II) oxide – selenium system was chosen. The conducted studies allowed the authors to find out a number of regularities that reveal the influence of storage technology, in particular, substrate temperature, deposition mode, residual vapor pressure in the system, sublayer parameters and quality of the source material on the electrophysical parameters of photovoltaic converters.
