 The realization of silicon carbide based applications demands for reasonable sized wafers of high crystalline quality.
-Despite the tremendous progress achieved in the fabrication of high purity SiC employing techniques like the modified Lely process for bulk crystal growth \cite{tairov78,tsvetkov98} or chemical vapour deposition (CVD) and molecular beam epitaxy (MBE) for homo- and heteroepitaxial growth \cite{}, available wafer dimensions and crystal qualities are not yet considered sufficient enough.
