FIG. 1.

Side-view backscattering geometry used Raman scattering measurements (not to scale).

FIG. 2.

(Color online) Polarized Raman spectra of BST thin film recorded under zero field (black) and under external electric filed 600 kV/cm (red). All Raman spectra are corrected for the Bose-Einstein temperature factor. Mode assignments correspond to the tetragonal symmetry under zero field. All spectra presented in these scattering geometries correspond to A′ modes of the monoclinic phase under external electric filed.

Image of FIG. 3.
FIG. 3.

Polarized Raman spectra of BST thin film recorded in crossed scattering geometries under external electric filed 600 kV/cm. All Raman spectra are corrected for the Bose-Einstein temperature factor.

Image of FIG. 4.
FIG. 4.

Wave number of the soft mode components as a function of external dc electric field. Open symbols increasing of the applied voltage, full symbols decreasing.
