The Raman measurements have been performed with the back-scattering geometry on the SiC films grown on Si (100) and sapphire (0001) by LPCVD. Typical TO and LO phonon peaks of 3C-SiC were observed for all the samples grown on Si and sapphire substrates
indicating the epilayers are 3C-SiC polytype. Using a free-standing 3C-SiC film removed from Si(100) as a free-stress sample
the stresses of 3C-SiC on Si (100) and sapphire (0001) were estimated according to the shift of TO and LO phonons.
