K. Cai et al., Evaluation of diamond-like carbon films deposited on conductive glass fromorganic liquids using pulsed current, SURF COAT, 130(2-3), 2000, pp. 266-273
Hydrogenated diamond-like carbon (DLC) films were deposited on conductive g
lass substrates from methanol, DMF and acetonitrile by liquid deposition us
ing a pulse-modulated source. The structure of the films was characterized
by XPS, Raman and IR spectroscopy. XPs showed that the main constituent of
the films was carbon. Raman and IR indicated that hydrogen was contained in
the films and bonded preferentially to sp(3) sites. From Raman spectra of
the films, we found that DLC was formed in most experimental conditions and
in some uncertain areas of the films deposited in DMF (1600 V) the diamond
peak was also detected. The films had high transmission ratios (> 70%) in
the range of 330-2000 nm with VIS/UV spectroscopy. The resistivity of the f
ilms was of the order of 10(10) Omega cm. (C) 2000 Elsevier Science S.A. Al
