Paper Abstract

The diamond-like carbon films, deposited by direct ion beam deposition method using mixture of C6H14 and H2 with and without silicon presence, have been investigated by Raman spectroscopy, X-ray photoelectron spectroscopy, ellipsometry, IR-visible-UV transmission, and electron paramagnetic resonance techniques. The D and G line widths and peak positions, integrated intensity ratio (ID/IG) in Raman spectra indicate these films being amorphous, mixture of sp2 and sp3 bonds. It has been found that a-C:H films formed while increasing substrate temperature and deposition ion energy tend to be graphite-like. Increasing of hydrogen content in gas mixture made these films more polymer-like with low content of dangling bonds. Traces of silicon increase sp3/sp2 ratio. The DLC films on silicon are able to greatly reduce IR reflection.
