| 中文摘要 | Phase-sensitive second-harmonic generation (SHG) is employed to investigate domain patterns of c-axis oriented xBi(2)Ti(4)O(11)-(1-x)Bi4Ti3O12 films on SrTiO3 (001) substrates. The film density increases with increasing Bi2Ti4O11 concentration up to x=0.39. No SHG signal was observed on the Bi2Ti4O11 film. Double peaks appear in the curves of the dependence of the SHG signal on the fundamental polarization (0degrees-180degrees), which suggests the net polarization of Bi4Ti3O12 domains oriented along SrTiO3 [110] and [1 (1) over bar0] directions. Under transverse electric field poling along the SrTiO3 [100] direction, the films with x=0.06 and 0.12 behave differently. The double peak intensities both increase monotonically with increasing +/-E fields in the film with x=0.06. However, they change reversibly for the film at x=0.12 with increasing voltage from -2.0 to +2.1 kV. Theoretical modeling suggests the possibility of 180degrees wall motion with an uncorrelated phase relation for the film with x=0.06, but 90degrees wall motion with a complete phase relation for the film with x=0.16. The large dielectric permittivity for the film with x=0.39 is assumed to come from the 90degrees wall motion. (C) 2002 American Institute of Physics. |
