Films with (240) preferred orientations were prepared on Pt-coated Si substrates by a reactive magnetron co-sputtering method followed by rapid thermal annealing. Crystallization temperatures between 600 and 700/spl deg/C resulted in square double hysteresis loops with large values of the maximum polarization (up to 70 /spl mu/C/cm/sup 2/). These very large values of induced polarization make such films attractive for energy storage applications. The phase transformations between the orthorhombic antiferroelectric phase and a rhombohedral ferroelectric phase, as well as ferroelectric-ferroelectric transitions were observed by studying the dielectric properties and the polarization-electric field hysteresis as a function of temperature. The behavior of the films is largely similar to that observed in single crystals, although the antiferroelectric-paraelectric phase transition temperature was increased by /spl sim/20/spl deg/C. Work on the strain change accompanying the field-induced transformation will also be reported.","PeriodicalId":14772,"journal":{"name":"ISAF '96.

The non-destructive AEs are not generated at maximum strain rate and maximum current in both piezoelectric and electrostrictive ceramics. The larger AEs are generated rigorously at high strain level, and they depend only on strain level. These results suggest that the non-destructive AE, which is attributed to the internal elastic energies, arise from lattice distortions with high internal stress field in the material such as piezoelectric, domain movement and electrostrictive deformation at high strain state.","PeriodicalId":14772,"journal":{"name":"ISAF '96.

However, the formation of perovskite phase for PZT thin film on polysilicon layer is difficult. The deposited thin film is very easy to crack. PT thin film was used as a transition layer between polysilicon wafer and PZT film. Crack-free PZT/PT composite thin film with perovskite structure was obtained by metallo-organic decomposition (MOD) method. By comparing the ferroelectric behaviors and C-V curves of PZT thin film on platinum which is widely used as bottom electrode in the study of ferroelectric thin films, the effects of polysilicon on crystalline structure and properties of the PZT/PT composite thin film were investigated.","PeriodicalId":14772,"journal":{"name":"ISAF '96.

Differential thermal analysis (DTA) carried out on the as-quenched samples confirms their glassy nature and shows a prominent exothermic peak at 400/spl deg/C. The X-ray powder diffraction (XRD) pattern of the heat treated sample could be indexed to an orthorhombic ferroelectric Bi/sub 2/VO/sub 5.5/ phase with the lattice parameters a=5.543, b=5.615 and c=15.321 A. The presence of nano-crystallites of bismuth vanadate, Bi/sub 2/VO/sub 5.5/ (BiV) dispersed in the glassy matrix of strontium tetraborate, SrB/sub 4/O/sub 7/ (SBO) is confirmed in the heat treated (at 400/spl deg/C for 12 h) samples, by high resolution transmission electron microscopy (HRTEM). The dielectric constant (/spl epsiv//sub /spl tau//), measured as a function of temperature, exhibits an anomaly around the transition temperature of the parent crystalline BiV. The /spl epsiv//sub /spl tau// of the glass-ceramic at 300K is comparable with that predicted by Maxwell's model and logarithmic mixture rule.","PeriodicalId":14772,"journal":{"name":"ISAF '96.

The samples were then tested for non-linearity by analyzing the fundamental resonance as a function of a DC bias field.
