The main results are following: - The spin-polarized conductivity of nanostructures of the ferromagnetic insulator-graphene-ferroelectric film type is calculated. - The phenomenological theory of photoinduced relaxation of charge carriers in 2D- MoS 2 is built. A relatively large effective electron mass in 2D- MoS 2 allows the creation of devices with channels of significantly shorter length (about 2.5-3 nm) than in traditional silicon MOSFETs. - Experimentally demonstrated that graphene due to its unique properties can be used as promising alternative nanocomplex for surface enhanced infrared spectroscopy. - It is established amplifying properties of the combined structure, which combines periodic waveguide -water structures and graphene nanoflakes. The level of gain changed depending on the molecular groups. - The amplifying effect of graphene nanoflakes and structures based on photonic crystals in Raman spectroscopy was revealed. - It is established that thermal conductivity of aqueous solutions of graphene- based nanocomposites and gold nanoparticles is higher than the thermal conductivity of graphene-based nanocomposites. With an increase in the concentration of nanopowder in the process of evaporation of water, excess entalpy, entropy and free energy decrease as a result of self-aggregation of nanobulbs. The results of the RRW (2019-2023) are published in 17 articles and 5 reports. Main keywords: metal-carbon nanostructures; hybrid nanostructures; graphene, ferroelectric, metalografene nanocomplexes; polymers; nanoparticle; nanocomposite; optical, plazmone and electrophysical properties.
