Dagestan State University

An interdisciplinary youth laboratory with research, technological and educational tasks for conducting fundamental and applied research in the field of photonics of nanoscale semiconductors. The main efforts are focused on the creation of functional photoactive nanomaterials of a new generation and the study of photostimulated processes of destruction of organic pollutants in heterogeneous systems.

The main area of ​​research in the Atomic and Molecular Layer Deposition Laboratory (ALD/MLD) of Dagestan State University is the synthesis of nanomaterials, in particular, nanofilms with thicknesses up to 100 nm. The laboratory has 4 vacuum atomic layer deposition apparatus of various types. 1 reactor with a flat-type reaction chamber with the ability to deposit nanofilms on flat substrates, 1 reactor with a volumetric reaction chamber, where it is possible to deposit nanofilms to volumetric samples, as well as 2 reactors with tubular reaction chambers, where it is possible to integrate quartz piezoelectric microbalances into the chamber, which are a unique tool for in situ monitoring of the processes occurring inside the reaction chamber during nanofilm growth. Both fundamental and applied research is carried out in the laboratory. New oxide, carbide, nitride and hybrid organo-inorganic nanomaterials are being developed for use in electronics, energy, ecology, nanomedicine and biotechnology. Comprehensive studies of the mechanisms of surface reactions and the resulting nanofilms are being carried out using quantum-chemical modeling, as well as such physicochemical methods of analysis as X-ray reflecto- and diffractometry, spectroscopic ellipsometry, X-ray photoelectron spectroscopy, etc. At present, technologies have been developed for deposition vanadium, titanium and molybdenum oxides, titanium-vanadium, titanium-molybdenum oxide nanofilms, silicon carbide, silicon-containing hybrid organo-inorganic nanofilms for use in high-temperature electronics, lithium-ion batteries, supercapacitors, photocatalysis, as dry lubricants, in nanomedicine. Methods have also been developed for producing polypropylene hernia meshes and surgical suture materials with high antibacterial properties by applying titanium-vanadium oxide nanofilms to them using atomic layer deposition; contact and intraocular lenses with improved resistance to ultraviolet radiation; protective nanocoatings on the surface of jewelry stones and products, etc.
