Abstract: Polycrystalline carbon nitride thin films were prepared on Si (100) by hot filament assisted rf plasma-enhanced chemical vapor deposition with negative bias methods. X-ray distraction (XRD) spectra indicate that the obtained CN films contain both crystalline β-C3N4 and β-C3N4, and a presently unknown structure. Some crystalline particles of 1-2μm in size with hexagonal cross section exist in the polycrystalline carbon nitride film. The maximum hardness of C3N4 thin film is 72.66GPa.
