The optical constants (complex dielectric function and refractive index) and the bandgap of SiC thin films were analyzed through spectroscopic ellipsometry in the 0.55–6.3 eV energy range. An increase in the bandgap (5.15–5.59 eV) and a corresponding decrease in the refractive index (2.97–2.77) were noticed with the increase of SiC film thickness from about 20–450 nm.
