摘要：

Pb0.99Nb0.02(Zr0.85Sn0.13Ti0.02)O3　(PNZST)　antiferroelectric　(AFE)　thick　films　are　successfully　deposited　on　silicon-based　Pt　and　LaNiO3　electrodes　by　a　sol-gel　method.　The　coexistence　of　ferroelectric　(FE)　and　AFE　phases　are　revealed　in　PNZST　films　by　XRD,　electric-induced　hysteresis　loops,　dielectric,　and　leakage　current　properties.　Comparing　with　PNZST/Pt　film,　larger　recoverable　energy　density　and　efficiency　are　obtained　in　PNZST/LaNiO3　film　due　to　the　lower　FE　phase　proportion.　It　is　analyzed　and　demonstrated　by　a　thermodynamic　model　of　AFE　and　FE　coexistence　system.　In　addition,　the　fatigue　behaviors　of　both　AFE　films　are　also　affected　by　the　proportion　of　the　coexisting　FE　phase.　PNZST/LaNiO3　film　exhibits　good　fatigue　resistance　on　energy　storage　even　after　1010　switching　cycles,　which　is　attractive　to　pulsed　power　applications.　©　2020　The　American　Ceramic　Society
