Raman scattering investigation of defects in thick homoepitaxial 4H-SiC films
Three types of defects, namely comet I, comet II and carrot, in thick 4H-SiC homoepilayer were investigated by the micro-Raman scattering measurements. Comet defects were originated from certain cores which caused by the point defects or the inclusions on the surface of the substrate. 3CSiC inclusions, which were not contained in carrot, were found in comet defects. The different distribution of 3C-SiC in comet I and comet II was investigated by using micro-Raman scattering measurement. The formation mechanisms of these three defects were discussed.
