Energy Storage Performance and Electric Breakdown Field of Thin Relaxor FerroElectric PLZT Films Using Microstructure and Growth Orientation Control
The Journal of Physical Chemistry C, 2018Co-Authors: Minh D. Nguyen, Evert Pieter Houwman, Guus RijndersAbstract:Thin relaxor–ferroElectric Pb0.9La0.1(Zr0.52Ti0.48)O3 (PLZT) films were deposited on Si substrates using Ca2Nb3O10 (CNOns) and Ti0.87O2 (TiOns) nanosheets as the growth template layer and SrRuO3 (SRO) as the base electrode layer, using pulsed laser deposition. XRD and cross-sectional SEM results show that the structure of the PLZT layers changes from very dense with (001)-orientation to columnar with (110)-orientation for CNOns and TiOns, respectively. The recoverable energy-storage density (Ureco) is nearly proportional to the critical Electric Breakdown field (EBD), which increases with PLZT film thickness. A very high Ureco value of 58.4 J cm–3 and energy-storage efficiency (η) of 81.2% were obtained at an EBD of 3400 kV cm–1 for the 1000 nm thick PLZT film on CNOns/Si, significantly higher than for the film on TiOns/Si (Ureco = 44.0 J cm–3 and η = 59.6% for EBD = 2800 kV cm–1). This excellent energy storage performance in the PLZT/SRO/CNOns/Si is due to the dense film structure and nearly hysteresis-f...

Electric Breakdown of longitudinally shocked Pb(Zr0.52Ti0.48)O3 ceramics
Journal of Applied Physics, 2011Co-Authors: Sergey I. Shkuratov, Evgueni F. Talantsev, Jason BairdAbstract:Electric Breakdown of longitudinally-shock-compressed Pb(Zr0.52Ti0.48)O3 (PZT 52/48) ferroElectric ceramics was experimentally investigated. It was found that a dependence of Breakdown field strength, Eg, of shocked ferroElectrics on the thickness of the element, d, ranging from 0.65 to 6.5 mm is described by the Eg(d)=γ·d-w law that describes the Breakdown of diElectrics at ambient conditions. It follows from the experimental results that the tunnel effect is a dominant mechanism of injection of prime electrons in the shocked ferroElectric elements. It was demonstrated that Electric Breakdown causes significant energy losses in miniature autonomous generators based on shock depolarization of poled ferroElectric elements.

PZT 52/48 ferroElectric ceramics: Depolarization and Electric Breakdown under longitudinal explosive shock
2011 IEEE Pulsed Power Conference, 2011Co-Authors: Sergey I. Shkuratov, Evgueni F. Talantsev, Jason BairdAbstract:Electric Breakdown within longitudinally explosively shocked Pb(Zr 0.52 Ti 0.48 )O 3 (PZT 52/48) ferroElectric ceramics was investigated. It was experimentally demonstrated that Electric Breakdown causes significant energy losses in miniature autonomous generators based on shock depolarization of poled ferroElectric elements. We found that a dependence of Breakdown field strength, E g , of shocked ferroElectric, on the thickness of the element, d, is described by the E g (d) = γ·d−w law which describes Breakdown measurements for a variety of diElectric materials at ambient conditions. The analysis of experimental results showed that the tunnel effect is a dominant mechanism of injection of prime electrons in the shocked ferroElectrics.

Electric Breakdown phenomena in CBN layers
Diamond and Related Materials, 1992Co-Authors: Jan SzmidtAbstract:Abstract The results of Electric Breakdown investigations of CBN layers formed on a silicon substrate are presented. The values of Breakdown voltages and critical Electric fields were determined and statistical analysis was carried out. A physical explanation of the observed phenomena was proposed.
