摘要：
(Pb0.97La0.02)(Zr0.95Ti0.05)O3 (PLZT 2/95/5) antiferroelectric films with (100) preferred orientation were successfully prepared on Pt-buffered silicon substrates via the sol-gel method. SEM results indicated that PLZT 2/95/5 antiferroelectric films with a thickness over 1,000 nm showed a crack surface. Also, it was found that, as the increase of the thickness, the field-induced strains were decreased gradually. Moreover, the frequency-dependent field-induced strains illustrated that the typical strains-electric field (S-E) curves with the maximum values could be obtained at a lower measurement frequency <500 Hz.
