Method for producing a conducting doped diamond-like nanocomposite film and a conducting doped diamond-like nanocomposite film

The present invention provides a method for producing a conducting doped diamond-like nanocomposite film containing, as basic elements, carbon, silicon, metal, oxygen and hydrogen. The film is produced as follows: a substrate is disposed in a vacuum chamber, and a voltage of 0.3-5.0 kV is applied to the substrate; a gas discharge plasma with an energy density of more than 5 kilowatt-hour/gram-atom of carbon particles is generated, and an organosiloxane compound is evaporated into the plasma; a beam of particles of a dopant is introduced into the plasma; and a film is grown on the substrate to produce a conducting doped carbon nanocomposite film with a predetermined relationship of atomic concentrations of carbon, metal and silicon. The film surface is coated with a silicon dioxide layer. A unidirectional alternating current is passed through the film in a current generator mode to effect electric thermal exposure of the film. As the result, a conducting doped diamond-like nanocomposite film having a multilayer structure is produced.
