WebSep 12, 1994 · 4H‐SiC bulk crystals were grown controllably by means of a modified Lely method. Homoepitaxial growth of 4H‐SiC was carried out by vapor phase epitaxy utilizing step‐controlled epitaxy on 4H‐SiC substrates prepared by the modified Lely method. The physical properties (electrical and optical properties) of 4H‐SiC epilayers were … Web4H-SiC single crystals grown by the seeded physical vapour transport method have been investigated. These crystals were grown on 6H-SiC seeds. The influence of the seed temperature, form and granulation of SiC source materials on the stability and efficiency of the 4H polytype growth have been investigated.
