Two phosphorus centers in SiC, an isolated P atom substituting for Si (P-Si) and a Si-site P-atom adjacent to a carbon vacancy (P-Si + V-C) are investigated by first principle calculations. It is shown that P-Si + V-C produces a singly occupied donor level which lies deeper than that of P-Si but above the double donor level of Ve. The calculated spin distribution indicates that the P-related paramagnetic resonance signals, P-1,P-2 and P-V, originate from this complex.
