Subject of research - processes of controlled change of mechanical, electrical and thermo-physical properties of nanostructured materials with polymeric and semiconductor matrices and nanofillers based on carbon, silicon and germanium, heat capacity and thermal conductivity of porous materials, spin-dependent effects of giant magnetoresistance and anisotropic magnetoresistance, Оbjective: to develop the physical basis for the creation of functional materials based on nanocarbon structures, semiconductor heterostructures and porous silicon by modifying their structural morphological, mechanical, magnetic, electro- and thermophysical properties. The main tasks are to study the processes of charge transfer and heat in chemically functionalized and mechanically modified interface areas of these structures; elucidation of regularities and mechanisms of spin-dependent transport in metal-modified carbon nanocomponents. Research methods: thermo-, electro-, photoelectric and magnetotransport research, photothermoacoustic and optical spectroscopy, X-ray diffraction analysis, electron microscopy, research of mechanical and acoustic properties, research of heat resistance. A new understanding of the physicochemical properties of graphene epoxy composites depending on the state of the interface regions is obtained. It has been shown for the first time that the placement of Si thin layers inside Ge quantum dots significantly (up to 40%) increases the Seebeck coefficient. It is suggested to use photothermoacoustic approach for simultaneous determination of heat capacity and thermal conductivity of porous materials.  Product Description popup.authors Borovyi Mykola О.
