摘要：

Ferroelectric Pb(Zr,Ti)O-3 heterolayered filing were prepared by the sol gel method. The adoption of PbZr0.2Ti0.8O3 (or PbZr0.2Ti0.8O3/PbZr0.8Ti0.2O3) buffer layers under a single-annealing process resulted in significant change in grain size, gradual change in composition, and Zr-rich regions in the middle of the heterolayered films. The large grain size and compatible interface between layers are good for the ferroelectric properties, and the Zr-rich layer contributes to not only the coercive field (E-c) lowering but also the improvement of fatigue endurance.
