Abstract:
It is demonstrated that polytype-homogeneous, thick ($>$ 100 $\mu$m) epitaxial 3C-SiC layers of good structural quality with diameters of no less than 25 mm can be grown on 6H-SiC substrates by sublimation epitaxy in vacuum. These layers can be used as seeds for growing volume 3C-SiC crystals by the modified Lely method.
