Abstract :
Antiferroelectric films of Sn doped Lead Lanthanum Zirconate-Titanate [(Pb, La)(Sn, Zr, Ti)O3, Sn-PLZT] with nano-grains were fabricated by aerosol-deposition (AD). The AD process produced highly dense films without visible pores. The polarization-electric field hysteresis loop and the phase transition behavior of PLZT with Sn doping into the B-sites were characterized. The grain sizes of the AD Sn-PLZT films, which were on the nano-scale, were controlled by the annealing temperature. Regardless of the compositions, the films with the nano-grains by the AD process showed less hysteretic behavior and larger stored energy. The Pb0.97La0.02(Zr0.85Sn0.13Ti0.02)O3 (PL-0.13) film deposited by AD and annealed at 750 °C for 1 h showed an energy storage capacity and efficiency of 13.0 J/cm3 and 78.9 %, respectively.
