Claim:
1. A method for epitaxial growth of a monocrystalline silicon carbide using a feed material for epitaxial growth of a monocrystalline silicon carbide, the feed material including a surface layer containing a polycrystalline silicon carbide with a 3C crystal polymorph, wherein upon X-ray diffraction of the surface layer, a diffraction peak corresponding to a (111) crystal plane and a diffraction peak other than the diffraction peak corresponding to the (111) crystal plane are observed as diffraction peaks corresponding to the polycrystalline silicon carbide with a 3C crystal polymorph, and wherein an average crystallite diameter calculated from a first-order diffraction peak observed by X-ray diffraction of the surface layer and corresponding to the polycrystalline silicon carbide with a 3C crystal polymorph is 700 Å or less.
