Abstract

The results of combined IR absorption and photoconductivity studies on hydrogen donors in ZnO and TiO2 are presented. It is shown that hydrogen donors in ZnO and rutile TiO₂ can be detected as Fano resonances in the photoconductivity spectra at the frequencies corresponding to the vibrational modes of these defects. In the case of anatase TiO₂ IR absorption lines at 3412 and 3417 cm⁻¹are assigned to the stretching local vibrational modes of a donor in the neutral and the positive charge states, respectively. Interstitial hydrogen is suggested as a tentative model for the defect giving rise to these vibrational modes.
