RAMAN SPECTROSCOPY OF TITANIUM DIOXIDE LAYERS A. FELSKE and W. J. PLIETH Freie Universitat Berlin, Institut fur Physikalische Chemie, Takustrosse 3, D-1000 Berlin 33, F.R.G. (Received 13 June 1988) Abstractn situ Raman spectra of electrochemically formed oxide films on Ti electrodes were measured. Since the space group corresponding to uranium dioxide is Fm3m , group theory predicts two vibrational modes for UO 2: a Raman active mode (T 2g) and an infrared active mode (T 1u). In such a way, the Raman spectrum of stoichiometric UO 2 presents a band at ~445 cm −1 assigned to the mentioned T 2g vibrational mode [ 61 ].Some of these spectra are shown in Figure 9. Therefore, the behavior of the uranium dioxide Raman spectrum as the oxidation degree increases can be described by the next features: (1) the apparition of different contribution bands at ~500–700 cm −1, typical of the hyperstoichiometric oxides UO 2+x (0 < x < 0.25),...

In this work the results of Linear Raman Spectroscopy experiments on hafnium dioxide (HfO2) thin films deposited by magnetron sputtering using different deposition conditions and post-deposition annealing are reported. Raman bands were identified considering the active symmetry modes expected from a tetragonal or monoclinic phase. All of the normal modes in SO2 are IR active and therefore can all be seen in the IR spectrum at the fundamental frequency. It is possible to observe other weak bands in the spectrum which are a result of overtones.
