主 题:antiferroelectric films freestanding energy storage
摘 要:Free-standing antiferroelectric Pb(Zr0.95Ti0.05O3(PZT(95/5)) thin film is fabricated on 200-nm-thick Pt foil by using pulsed laser deposition.X-ray diffraction patterns indicate that free-standing PZT(95/5) film possesses an α-axis preferred *** critical electric field for the 300-nm-thick free-standing PZT(95/5) film transiting from antiferroelectric to ferroelectric phases is increased to 770 kV/cm,but its saturation polarization remains almost unchanged as compared with that of the substrate-clamped PZT(95/5) *** energy storage density and energy efficiency of the substrate-clamped PZT(95/5) film are 6.49 J/cm^3 and 54.5%,*** contrast,after removing the substrate,the energy storage density and energy efficiency of the free-standing PZT(95/5) film are enhanced up to 17.45 J/cm^3 and 67.9%,respectively.
