The transformation of energy in the graphene-Ge (111) adsorbate-substrate system for a number of temperatures has been theoretically and experimentally investigated. The binding energy of oxygen-containing functional groups with the base plane and the edges of graphene nanolith is calculated. The interaction of molecular oxygen with a silicon surface coated with a submonolayer coating Mn, at room temperature, was experimentally investigated. The relative grain boundary energy in silicon unpolished and doped with silicon films with different structure is investigated. It is shown that the least relative grain boundary energy is in non-alloy films with dendritic structure. The study of the kinetics of relaxation of the photocurrent through the pSi-CdTe-ZnO heterostructure and the changes of the reciprocal current under the influence of adsorption of ethyl, isopropyl alcohol and water molecules on its surface are carried out. It was found that light with a wavelength of 458 nm can significantly increase the adsorption sensitivity of the samples to a couple of alcohols. Based on the results of the experimental dependencies I = f (t) and computer modeling of the zone diagram of the pSi-CdTe-ZnO heterostructure, a possible explanation of the mechanism of influence of the radiation of the optical range on its adsorption sensitivity is proposed. A generalized model of mutual phase synchronization of spin-torque magnetic nanooscilators. Different modes of operation of spintronic magnetic microwave detectors are investigated. The magnetic and microwave properties of thin ferrite films and composite magnetic film structures were studied and application of the investigated phenomena in devices of spintronics was considered. The solution of the inverse problem of focusing light through a strongly disordered medium is obtained. Experimental focusing is carried out through a layer of titanium dioxide using an amplitude modulator. The diffraction limit of resolution is obtained.
