popup.description1
Formation of scientific and technical bases for significant increase of productivity of processes and maintenance of competitiveness of nanostructures of domestic production by development and introduction of modern plasma methods of growth with realization of new and known technological decisions for maintenance of qualitative characteristics of nanostructures of various dimensionality.
popup.description2
The project is devoted to the problem of increasing the efficiency of processes of formation of nanostructures of different dimensions by developing scientific foundations for the creation of a new generation of plasma systems of nanotechnology. Systematic theoretical and practical studies of the influence of plasma make it possible to significantly (tens of times) increase the speed of growth processes in comparison with the currently common methods. During the implementation of the project, an experimental and theoretical study of the growth of nanostructures was carried out with the use of glow, arc, radio frequency and microwave discharge plasma, as a result of which methods of controlling the influence of ion bombardment on the processes of obtaining nanostructures were proposed; formulated recommendations on rational processing methods for obtaining various nanostructures (use of certain plasma sources, their modes of operation, placement schemes, order of inclusion, etc.); developed recommendations on the application of various schemes of electric power supply to the sample for the growth of nanostructures; for the first time, technological recommendations were formulated regarding modes of formation of certain nanostructures, which are of great importance in industry and a significant probability of practical implementation (copper oxide nanowires for sensitive elements of Raman spectroscopy of explosive or harmful substances, vertical graphene structures for supercapacitors); received further development of the theory and technique of plasma surface treatment using arc plasma sources, which made it possible to offer recommendations for obtaining nanostructures on the surface and in the near-surface layers of materials; proposed new methods of forming an active plasma medium by using a spark discharge.
