The electronic structure of the {113} extended defect in electron-irradiated silicon is investigated by high-resolution transmission electron energy-loss spectroscopy (HR-EELS) combined with the tight-binding and ab initio calculations. We have found that the peak in the imaginary part of the dielectric function, ε2 in the defect-rich region shifts at 2 ∼ 2.5 eV. We attribute this result to the nonvertical interband transition between the defect-localized states at the band edges. The detection of the extended defect in semiconductor in ε2, has been demonstrated for the first time in this study.
