抄録

We report luminescence from spin triplet states of excitons bound to interstitial carbon-interstitial oxygen defects in silicon. The peak, which we call C_T-line, has an energy 2.64 meV lower than 790 meV (C-line), and splits into three peaks by application of magnetic field. Moreover, its peak position does not depend on the angle between the magnetic field direction and crystallographic orientation indicating the quenching of orbital angular momentum of the hole bound to the defect. These observations lead us to conclude that the C_T-line is the photoluminescence from a triplet state.
