The relationship between the growth of isolated carbon (C) content and the rise of broad photoluminescence (PL) band intensity in а-SiOC:H films and а-SiOC:H nanopowders has been established. It was proved that PL emission arises from C nanodots distributed over the SiO2:C surface. The increase in PL intensity in Al2O3:C nanopowders was found to be caused by the formation of SiO2:C on the Al2O3 particle surface. The charge carrier transport in graphene layers deposited on SiO2 was studied. It was found that the charge carrier distribution at high temperatures in graphene is determined by phonon component. A working formula for the capacity of contact metal-graphene film was obtained. A simple method for synthesis of graphene flakes from solid precursor has been developed. The new C structures in the form of graphene bubbles, multi-layer C tubes and "stars" formed after gamma-irradiation were observed for the first time. The significant decrease of specific resistance of graphene oxide by thermal annealing at low temperatures was revealed and explained. The kinetic Monte-Carlo method for investigation of growth and evaporation processes nanoparticles to/from nanotubes as well as for the study of the nanorods non-stability leading to their transformation to ordered nanocluster chains was developed.
