The article suggests directions for improving the quality of traditional as well as the development of new semiconductor materials and different types of metallization. The use of epitaxial compositions for the production of photoelectric converters promises particularly great prospects. The tendencies of creation of the most complex electronic devices on the basis of multilayer epitaxial structures are clearly shown. At the same time, very high requirements are imposed on the electrophysical properties and perfection of the structure of each layer; the problems of creating perfect and sharp p-n junctions and heteroboundaries on large areas of epitaxial compositions are posed.en-USPlateDefectsEpitaxial compositionsContact systemsPhotoelectric converters
