The research methods are the infrared absorption, photoluminescence, photovoltaics and electrical methods. Computer modeling of physical properties of nanostructures, comparison of theoretical and experimental results. Results: - developed original technologies for the formation of nanoscale silicon and metal clusters and thin layers of semiconductors, placed both on the free surface and embedded in dielectric matrices of various types; - photoelectric, luminescent, and surface properties of nanosized semiconductor structures have been studied in detail, important peculiarities of physical processes occurring in nanostructures have been established; - proposed theoretical models for calculating the parameters of semiconductor nanocrystals and the efficiency of photoelectric transformation; - silicon structures for use as photovoltaic converters of solar energy were studied and criteria for obtaining extremely high parameters of devices were formulated and gas sensitivity of MIS structures was increased using metal nanocomposite catalysts, which allowed to form prototypes of sensors with high gas sensitivity. Predictive assumptions for the development of research objects - optimization of technologies for the formation of nanocluster systems with specified parameters and small size variation for use in devices of nanoelectronics, optoelectronics, nanophotonics, photoelectrics and sensors.
