Kopsavilkums

Lead zirconate titanate films (PZT) of the morphotropic phase boundary composition were prepared using a diol-based sol-gel route modified by introducing 1-5 mol% PZT nano-seeds (with the same composition as the films). Thin films derived from unseeded and seeded precursors were fabricated on platinised silicon substrates (Pt/Ti/SiO2/Si). The effects of the concentration of seeds on the hysteresis behaviour and fatigue endurance were investigated. Seeded films showed a clear improvement in fatigue properties compared with unseeded films. The seeded films could withstand more than 109 switching pulses while unseeded films degraded after about 107. The possible mechanism is postulated and related to the microstructure, preferred orientation, and the interface state of the PZT thin films.
