Abstract

The electronic properties of the (001) Si/SiO2 Pb1 defect are the subject of considerable controversy. We present spin-dependent recombination results which indicate most strongly that the Pb1 centers have levels in the Si band gap. Our results suggest that the Pb1 correlation energy is smaller than that of the more widely studied (001) Si/SiO2 defect called Pb0.
