Notes:
In EPR (electron paramagnetic resonance) identification of point defects, hyperfine (HF)interaction is decisive information not only for chemical identity but also for the local geometry andthe electronic state. In some intrinsic defects in SiC, the wave function of the unpaired electronextends quite unevenly among major atoms comprising the defects. In such a case, the determinationof the number of equivalent atoms and the chemical identity (Si or C) of those atoms even with weakHF splitting are useful to compare with HF parameters obtained theoretically. For vacancy-relateddefects of relatively deep levels, the sum of the spin densities on the nearest-neighbor shell is found tobe 60-68%
