Description
| - The ferroelectric soft mode behaviour was studied in several SrTiO3 (ST) films on sapphire substrates using far infrared (FIR) transmission measurements and in the bulk ST ceramics using Raman and FIR reflectivity measurements down to 15 K. The recently established dramatic differences in softening and soft mode width compared to single crystal behaviour were confirmed in all the cases. Clear evidence of polar cluster appearance in the pure bulk ceramics indicates that the main reason for the observed differences in thin films are inhomogeneities due to the appearance of polar clusters or even a macroscopic ferroelectric transition at about 130 K in the case of well oriented injection MOCVD film.
