It is studied the structure of nano-sized diamond-like carbon films on silicon surface with the density 3,3 g/cm3 and surface roughness 1,5 m obtained by graphite magnetron sputtering, and β-SiC films synthesized by ion-beam sputtering of two-component silicon/graphite target. The presence of sharp film-substrate interface allows one to study composition, density, and thickness of C and SiC film with the use of X-ray reflectometry for spectral lines CuKα (0,154 nm) and CuKβ (0,139 nm). Numerical simulation is also performed, the results obtained fit the experimental data.
