It is well accepted that reorientation of the spontaneous polarization will cause soening of the A 1 (TO 1 ) mode ($ 130 cm À1 ) when the AFE O changes into AFE T .…”

“…Figure b reveals the frequency-dependent dielectric properties of various samples at room temperature from 20 to 2000 kHz. Apparently, the dielectric constants of all the samples are reduced slightly in the overall frequency range, which is in accordance with the law of general dielectrics. − Moreover, the dielectric constant of the APA films is lower than P films, but still maintains a high value close to 200, which is ascribed to the large dielectric constant of PLZST and the partial crystallization of AO.…”

In this work, the Pb 0.97 La 0.02 Zr 0.85 Sn 0.12 Ti 0.03 O 3 (PLZST) antiferroelectric composite films with aluminum oxide (Al 2 O 3 ) film as a double-blocking layer have been designed and successfully prepared via the sol−gel method. The energy storage characteristics, electrical properties, charge−discharge performance, and temperature stability of the composite films were studied systematically. As a result, by engineering the Al 2 O 3 double-blocking layer on both sides of the antiferroelectric films, the breakdown strength of the composite films increases by 126% from 66.5 to 150.4 kV/ mm and the recoverable energy storage density was significantly enhanced from 10.2 to 27.7 J/cm 3 . Meanwhile, the discharge period has been measured as well, which is only 104 ns, resulting in a large peak current density of 180 A/cm 2 and an extremely high peak power density as high as 90 MW/cm 3 under 100 kV/mm. Furthermore, the composite films exhibited high temperature stabilities; the peak current density and the peak power density change is less than 15% when the temperature range varies from 30 to 100 °C. These results demonstrate that the PLZST films with double-blocking structures are promising candidates for pulse power applications.

“…Recently, many studies have been conducted to increase the breakdown of the electric field and energy storage density. Representatively, many research results have been reported on the composition of (Pb, La)(Zr, Sn, Ti)O 3 (PLZST) [9][10][11]. PLZST has a structure in which Sn 4+ is substituted for the B-site, which is an element site with a similar ionic radius in the PLZT composition.…”

(Pb, La)(Zr, Ti)O3 (PLZT) with antiferroelectric properties can be applied as a capacitor whose capacitance increases in a high electric field. From this, we obtained a high sintering density at 950 °C by adding low-temperature sintering additives, 8.0 wt% of PbO and 2.5 wt% of ZnO, simultaneously to a (Pb0.88, La0.12)(Zr0.86, Ti0.14)O3 composition. The change in electrical characteristics was confirmed in terms of Sn4+ substitution, resulting in no change in the sintering density by Sn4+ substitution. However, as the amount of Sn4+ substitution increases, the dielectric constant gradually decreases from 1300 to 700, and the grain size decreases from about 4 to 1 µm in terms of microstructure. In the crystal structure analysis, the general formation of a single perovskite structure was confirmed. The results of the hysteresis curve measurement revealed that the breakdown electric field increases from 4 to 9 kV·mm−1 as the amount of Sn4+ substitution gradually increases. However, polarization decreases in the same way as the permittivity trend. The composition exhibits excellent electrical properties when the ratio of Sn4+ is 0.4: a high energy storage density of 3.5 J·cm−3, energy efficiency of 80%, and breakdown electric field of about 8.5 kV·mm−1.
