Numerical results of A1, T2 Symmetric sp3 bonded deep level wave function in 3c-SiC are obtained Using the Koster-Slater Green's function method developed in reference [1-4]. The wavefunction change with the energy of the defect and occupation probability on 0,1,2,...8 shells around the defect are predicted. The constant of hyperfine structure for 3c-SiC:B are calculated and compared with experimental data.
