Jm. Yanezlimon et al., CHARACTERIZATION OF CARBON-FILMS MICROSTRUCTURE BY ATOMIC-FORCE MICROSCOPY AND RAMAN-SPECTROSCOPY, Journal of applied physics, 76(6), 1994, pp. 3443-3447
Atomic force microscopy has been used to study the surface irregularit
ies of hydrogenated and unhydrogenated carbon films grown by rf-powere
d glow discharge and dc-magnetron sputtering, respectively. In general
films produced with the latter technique have rougher surfaces. In gl
ow discharge produced samples, roughness can be reduced by increasing
rf power during deposition. In sputtered films surface roughness is re
duced by either lowering substrate temperature or reducing the power d
ensity during deposition. The relation between the microstructure and
the crystalline state was done using Raman scattering.
