In this work, the field distribution in structures such as a gold grating, a graphene layer, and a silicon substrate was studied. The conditions for maximum electromagnetic field distribution (absorption) by this structure to use in photonics and electronics devices were established. The magnitude of the electromagnetic field of a gold diffraction grating with a graphene layer increases with decreasing slit width. At the same time, an increase in the period leads to small changes in the electromagnetic field distribution.

The investigation results of silver, palladium and gold nanoscale particles deposition on the silicon surface in the DMSO and DMF media are presented. The influence of organic aprotic solvents on the geometry of metal particles and their distribution on the substrate is described. It is shown that solutions of stable metal complexes ([Ag (CN)2] – , [AuCl4] – ) are the main factor in the formation of discrete nanoparticles with a small range of sizes and uniform distribution along the substrate surface, as well as nanostructured films.

The controlled synthesis of parts of noble metals of a given morphology, shape, size and distribution on the floor emphasizes the important prerequisite for the creation of complex structures, for example nanowire, are one of the most promising materials for the creation of modern devices.
