Abstract


Silicon carbide as a material for electronic devices still has Substantial problems concerning its structural quality and defects. It has been shown that dopants call have a big influence on structural properties like poly-type stability and dislocation statistics [1]. We will discuss the effect of an isoelectronic dopant in silicon carbide. Germanium, being a member of the 4(th) group in the periodic table of elements like silicon and carbon, will not influence the electrical properties of the material such as e.g. aluminum. In Our experiments we reached concentrations of up to 1*10(20) cm(-3). We have observed all impact on the polytype stability during sublimation growth with in-situ germanium incorporation. We investigated all influence on the dislocation statistics during growth and, hence, varying germanium concentration. We found only a slight decrease in mobility during Hall measurements but no severe changes in electrical properties of the material.
