Abstract

The absorption coefficient of β–SiC is measured by the transmission technique. β–SiC films are grown on Si substrates by chemical vapor deposition using a buffer layer between β–SiC and the substrate. The absorption coefficient value ranges from 10 to 5.5 × 104 cm−1 in the energy range between 2.42 and 4.4 eV. The bandgap of β–SiC films investigated in this study ranges between 2.13 and 2.32 eV.
