The interaction of super screw-dislocations, or micropipes, in PVT grown SiC crystals has been studied by Synchrotron Radiation radiography. The reduction in micropipe density via reactions of coalescence, annihilation and transformation of micropipes has been observed. The reactions have been described quantitatively based on the micromechanics of these defects.X115sciescopu
