A SiC single crystal is grown by physical vapor transport (PVT) in a graphite growth chamber, the interior of which is charged with a SiC source material and a SiC single crystal seed in spaced relation. During PVT growth of the SiC single crystal, the growth chamber further includes Ce. The SiC single crystal grows on the SiC single crystal seed in response to heating the interior of the growth chamber to a growth temperature and in the presence of a temperature gradient in the growth chamber whereupon the temperature of the SiC single crystal seed is lower than the temperature of the SiC source material. The Ce can include either Ce silicide or Ce carbide.
