Abstract: In a method of SiC single crystal growth, a SiC single crystal seed and polycrystalline SiC source material are provided in spaced relation inside of a graphite growth crucible along with at least one compound capable of forming SiO gas in the growth crucible. The growth crucible is heated whereupon the gaseous SiO forms and reacts with carbon in the growth crucible thereby avoiding the introduction of carbon into the SiC single crystal before and during the growth thereof and the SiC source material vaporizes and is transported via a temperature gradient in the growth crucible to the seed crystal where it precipitates and forms a SiC single crystal.

Abstract: In a physical vapor transport method and system, a growth chamber charged with source material and a seed crystal in spaced relation is provided. At least one capsule having at least one capillary extending between an interior thereof and an exterior thereof, wherein the interior of the capsule is charged with a dopant, is also provided. Each capsule is installed in the growth chamber. Through a growth reaction carried out in the growth chamber following installation of each capsule therein, a crystal is formed on the seed crystal using the source material, wherein the formed crystal is doped with the dopant.
