Реферат:	eng: A homogeneous diamond-like film was obtained on an area of 75 x 25 mm(2). Study of the film structure, using transmission electron microscopy and Raman spectroscopy, showed a mixture of carbon atoms with sp(2)- and sp(3)-bonds. Structure of carbon film is determined by the presence of randomly oriented carbon clusters bound by diamond sp(3)-bonds (tetrahedral amorphous carbon, to-C). Electron diffraction patterns demonstrate strongly distorted interfacial distances. Raman spectra show that there are carbon atoms with graphite sp(2)-bonds in the film, but a signal of graphite crystal lattice is absent in electron diffraction: This implies that hexagonal units are not shaped into a graphite crystal lattice. Broad D-band in Raman spectra shows strongly distorted carbon bonds in graphite. If diamond phase dominates, the space between diamond clusters is filled with carbon atoms with sp(2)-bonds (turbostratic structure). Thus, diamond areas are bound into a single discontinuous aggregate of carbon diamond-like film.
