摘要：

First-principles theory shows that the substitutional-interstitial copper pair in Si (Si-Cu-s center dot Cu-i) has a metastable state with Cu-i very near a tetrahedral interstitial site in a trigonal Cu-s-Si center dot Cu-i configuration that exhibits three low-frequency pseudolocal vibrational modes. The lowest of them, at 40 cm(-1), has A(1) symmetry and is the likely source of the phonon sidebands observed at 52 cm(-1) in the photoluminescence band of a defect known as Cu-*(0).
