The activation energies of acceptor and donor defect states in this ordered defect compound were calculated by using a simple model which was based upon effective-mass theory for single, double and triple point defect centers. It was found that the values of these energies for shallow and moderately deep levels were in reasonable agreement with those deduced from experimental data.
