    The contribution of the SiO2/Si interface structure to optical absorption below the optical absorption edge of fused quartz was studied by measuring the reflectance of thermally grown ultrathin silicon oxide films. From the modified Kramers-Kronig analysis of reflectance, it was found that optical absorption at the photon energy of 7.8 eV arises from SiSi bonds in the oxide film within 1.4 nm of the interface. The approximate areal density of SiSi bonds is 7 × 1014 cm-2 and is approximately equal to the areal density of silicon suboxides determined by X-ray photoelectron spectroscopy.
