Abstract

Charge–discharge properties of an La-modified Pb(Zr,Sn,Ti)O3 (PLZST) antiferroelectric (AFE) ceramics capacitor were investigated by directly measuring its hysteresis loops and pulse discharge current–time curves under different electric fields. Large increments in polarization and discharge current were observed when the electric field increases from 3 to 3.5 kV/mm. Under 4 kV/mm, the first current peak of this AFE ceramics capacitor (static capacitance around 4.4 nF) can surpass 1.1 kA, and more than 80% electric charge stored can be released in <65 ns. Moreover, this AFE ceramics capacitor can withstand 2000 times of charge–discharge cycling with no significant degradation of properties under 3.5 kV/mm.
