Purpose: the development of a set of measures to establish the relationship between the physical characteristics and morphological properties of nanostructures formed on the substrates of A3B5 and A2B6 single-crystal semiconductors, the theoretical justification of the expediency of using the obtained nanostructures as a material for photoelectric devices for obtaining and storing energy, developing the foundations of the system for ensuring environmental safety and energy efficiency . Nanostructured layers of semiconductors were obtained by the method of electrochemical and photoelectrochemical etching. The morphology of the surface was investigated with the help of a scanning electron microscope, the chemical composition of surface layers by electron spectroscopy for chemical analysis (EDAX), X-ray spectroscopy. To study the quality of nanostructures, the system analysis method was used. A criterial apparatus for evaluating the quality and appropriateness of using nanostructured semiconductors in a FEP and supercapacitor is developed. Correlations between prescription and technological factors and the morphology of nanostructures have been established experimentally. To explain the acquisition of new properties by semiconductors in their nanostructuring, a mathematical model was developed, on the basis of which a nomenclature of quality indicators for nanostructures was determined. A generalized criterion for the quality of nanostructures synthesized on the surface of semiconductors is developed, which will make it possible to produce nanostructures for FEP in industrial scales. For the first time, studies on the production of nanostructured semiconductors, the determination of their characteristics and their application in power engineering, were carried out in the context of methodologically sound environmental safety of Ukrainian urbosystems. Conceptually (theoretically justified), indium phosphide and film cadmium telluride are combined for use in a hybrid supercapacitor. It is shown that the decrease in stresses arising as a result of the discrepancy between crystal lattices is possible due to the use of a porous layer of indium phosphide as a buffer layer. Methodological fundamentals of the environmental safety management system of the process of vital activity of the urban system are developed using the developed types of nanostructured semiconductors. A good practical result is the development of draft normative and technical documentation, in the form of methodological recommendations, draft standards of the enterprise, draft code of established practice, descriptions and passports of standard samples of the enterprise, etc. Product Description popup.authors Єфименко Юрій Олександрович Гнатюк Віталій Васильович Дейнеко Наталя Вікторівна Ковачов Сергій Сергійович Кондратенко Олександр Миколайович Онищенко Сергій Вікторович popup.nrat_date 2020-04-02 Close
