Abstract:
1. An apparatus for the production of bulk silicon carbide single crystals, comprising: a chamber for subliming a silicon carbide source material and transporting the sublimed silicon carbide source material to a silicon carbide crystal growth surface; a silicon carbide seed crystal having a silicon carbide crystal growth surface within said sublimation chamber for supporting the growth of a silicon carbide single crystal from said sublimed silicon carbide source material, wherein said silicon carbide crystal growth surface is oriented substantially perpendicular to the flow of sublimed silicon carbide source material; and a silicon vapor species outlet located in said sublimation chamber for allowing the preferential release of atomic silicon (Si) vapor species from within the sublimation chamber to a region outside of the sublimation chamber while retaining other vapor species inside the sublimation chamber.
