The purpose of the Project is the experimental and theoretical study of electronic vibrational processes in 1D and 2D nanosystems to establish the influence of the type of symmetry, dimensionality, and changes in structure on the regularities of the course of nonlinear resonant wave interactions in these systems, which is the basis for developing fundamental principles for creating polymer multicomponent nanocomposites with controlled and improved optical, electrical, magnetic, etc. properties depending on the scope of application. To achieve the goal, it is necessary to perform the following tasks: to study the energy spectra of vibrational and electronic elementary excitations of crystals and periodic nanostructures of hexagonal transition metal dichalcogenides (DHPM), fullerenes and their functionalized modifications, polymer nanocomposites using optical spectroscopy methods depending on morphology, phase composition, structure; and using quantum chemistry methods to calculate the electronic configurations, positions of energy levels of the ground and higher excited states, and energies of optical transitions for the systems under study. The idea of the Project is to develop scientific approaches to the creation of multicomponent nanocomposites with predicted properties for new applications and to create such a research methodology that would allow for the full interpretation of the experimental results obtained. The hypothesis of the Project is the selection of the filler material and the influence of morphology, phase composition, structure. Product Description popup.authors Doroshenko Iryna Yu.
