The Raman spectra revea that the anodic oxide film is primarily composed of an anatase type of TiO2. From the relation between the Raman band intensity, film thickness, and surface morphology, it is likely that the film changes from the amorphous state to the crystalline state beyond a certain critical potential.The Electrochemical Society1986engjournal articleVoRhttp://hdl.handle.net/2115/62179https://doi.org/10.1149/1.21084520013-46511945-7111J.
