    Abstract:
    Defects present in β-SiC thin films epitaxically grown on hexagonal 6H α-SiC substrates via chemical vapor deposition have been characterized by transmission electron microscopy. These defects are different from those previously observed in β-SiC films grown on (100) silicon, which were predominantly stacking faults and microtwins. The most common defects in the films grown on α-SiC were large domains rotated 60° with respect to each other and were identified as double positioning boundaries. These boundaries are a special type of incoherent twin boundary. Differences observed in films grown on either the silicon or carbon face of the 0001 α-SiC are characterized as a function of the mechanism of formation of the defects and type of substrate used for growth.
