The incorporation of hydrogen within ultrananocrystalline diamond/amorphous carbon composite films has been investigated
by nuclear reaction analysis (NRA) and Fourier transform infrared spectroscopy (FTIR). The film bulk contains ca. 7.5-8% H (for a deposition temperature of 600 °C), while the H concentration in the surface region is considerably higher.
FTIR measurements show that the hydrogen-rich surface is formed right at the beginning of the deposition process and grows outward as the film thickness increases. It can thus be concluded that surface hydrogen species play an active role in the formation of ultrananocrystalline diamond/amorphous carbon films.
