ABSTRACT Background doping as well as intentional doping using nitrogen and trimethylaluminum have been investigated for 4H-SiC epitaxy on offcut Si face, C face, and a-axis substrates over a wide range of C:Si ratio. Smooth morphology can be obtained at a C:Si ratio of 2.0 on a-axis substrates but not on Si or C face material. Background doping levels of
