Abstract
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.
