Defects in UHV sublimed silicon carbide can be traced to the relatively low growth temperatures and the high graphitization rates in the out of equilibrium UHV sublimation process. Whereas increased growth temperature will anneal vacancies and grain boundaries, the UHV growth method still leads to unacceptable high sublimation rates.
