UV–vis transmittance spectra, absorption coefficient versus energy, and ( αhν )1/3versus energy ( hν ) . (a) UV–vis transmittance spectra and the inset show the energy optical bandgap from SiO x films as a function of growth temperature, (b) absorption coefficient versus energy, and (c) (αhν)1/3 versus energy (hν). The dashed lines show the linear fit of the straight part.
