Description:
Multifunction alantiferroelectric (Pb 0.92- x Ba 0.05 La 0.02 Dy x )(Zr 0.68 Sn 0.27 Ti 0.05 )O 3 multilayer ceramic capacitor (MLCC) was prepared successfully by the tape-casting method. The MLCC with ten thick layers exhibits compact structure, excellent energy-storage and strain properties. For energy-storage performance, the pulsed discharge current reveals that the stored energy can be released in a quite short time of about 600 ns. The maximum discharge energy density was obtained in the sample with x = 0.04 at 300 kV/cm, which was 3.8 J/cm 3 calculated by the hysteresis loop and 2.7 J/cm 3 by the pulsed discharge current, respectively. Meanwhile, the MLCC possesses large strain property, where the sample with x = 0.04 shows a high field-induced strain of 0.71% at room temperature. In addition, the temperature dependence of energy-storage and strain demonstrates that the MLCC has good temperature stability. The results indicate that the multifunctional MLCC can be a promising candidate for the application in energy and sensor fields. This article is protected by copyright. All rights reserved.
