WebAug 13, 2024 · Generally, it is very difficult to grow large diameter 4H-SiC single crystal with single polytype by Physical Vapor Transport (PVT) growth method and mostly it ends up with the presence of some other polytypes (viz. 6H, 15R). This paper presents the various comprehensive polytype identification techniques in SiC wafer grown by PVT method. … Webdouble stacking faults DSF were found. The DSF in 4H is equivalent to a 5-layer inclusion of 3C. Since 3C and 4H SiC have different band gaps by about 0.9 eV, this leads to quan-tum wells of 3C in 4H6 and the question arises whether such systems can have gaps lower than any other polytype.
