    • 2, i.e., a relaxed and an unrelaxed type (H. Imai et al., Phys. Rev. B 38, (1988)12772). The former and the latter give optical absorption bands at ∼ 7.6 and 5 eV, respectively, and the oscillator strength of the former is several times as large as that of the latter. However, the apparent intensity at 5eV in the induced absorption spectra is ∼ 1/10 as small as that at 7.5 eV. In addition, PORs also give a band at ∼ 5 eV [12]. Therefore, the contribution of the unrelaxed oxygen vacancy to the total oxygen vacancy concentration can be neglected as a first approximation.

    • note
    • NBOHCs are created from the Si-OH precursor by X, γ-ray or unfocused ArF laser irradiation. Although it was recently suggested [16] that NBOHCs are created by the reaction of E′ center with an interstitial oxygen atom created from the intrinsic structure, here we did not regard a NBOHC as an oxygen interstitial. However, this difference in choice does not bring about a significant influence is the following discussion and conclusion because the concentration ratio of NBOHCs to POR is ∼1.
