Rudchenko S. Structure and properties of films deposited from flows of C60

Experimentally determined values of elastic modulus (E = 14,1 GPa) of polycrystalline films fullerites C60 with thickness about 4 microns deposited on silicon substrates and alkali halide crystals, conform to theoretical calculations modulus mono- and polycrystalline fullerites C60, and hardness values (H = 0,42 GPa) that was obtained for polymerized fullerites. The regularity of structure formation of thin carbon films obtained from accelerated ion flow fullerene C60 with an average ion energy of 5 keV at substrate temperature (Тs) 100-400oC was investigated. When substrate temperatures up to 200°C formed diamond-like carbon films (DLC). At Тs = 200оС begins the formation of graphite phase in the growing carbon films. At Тs = 400°C in the first obtained and investigated experimentally the new high-strength (E = 370 GPa, H = 50 GPa) nanocomposite carbon material with high conductivity (3000 Sm/m) and photoabsorption spectrum covering the visible and UV ranges (Eg ~ 1 and 3,5eV), which consists of graphite nanocrystals surrounded by amorphous carbon phase. Heterosystem based on fullerites C60 and diamond-like carbon film (glass/ITO/DLC/C60/Ag) with photovoltaic effect was developedin the first. The possibility of modifying the structure and properties of diamond-like carbon films used in heterosystems by forming quantum dots on the surface was shown.
