Abstract
Spintronic and electronic properties of a neutral oxygen-vacancy (O-V) center, an isoelectronic defect similar to the negatively charged nitrogen-vacancy center in diamond, were studied by combining first-principles calculations and a mean-field theory for spin hyperfine interaction. It is elucidated that the neutral O-V center is stable in the p-type diamond and possesses an S=1 triplet ground state and four spin-conserved excited states with the spin coherence times in an order of second at T=0K. The results indicate that the neutral O-V center is another promising candidate for spin coherent manipulation and qubit operation.
