Abstract

A silicon carbide epitaxial film, grown on an offcut surface of a SiC crystalline substrate of hexagonal crystal form, having an offcut angle of from about 6 to about 10 degrees, toward the <1100> crystalline direction of the substrate. The resultant silicon carbide epitaxial film has superior morphological and material properties.
