摘要
Three BaTiO3 films of different thicknesses and way of preparation on (0001)-oriented sapphire substrate were studied by means of far infrared and micro-Raman spectroscopy in the 10-520 K temperature interval. The data allowed us to evaluate the complex dielectric function of the films in the 20-300 cm(-1) frequency range and discuss their phase transitions and lattice dynamics.
