摘要
Abstract
(1-x)CaBi4Ti4O15-xBi(Fe0.93Mn0.05Ti0.02)O3(CBT-xBFMT,x=0,0.05,0.10,0.15)solid solution films were successfully prepared on Pt(111)/TiO2/SiO2/Si substrates using metal organic decomposition combined with spin coating technology.And the energy storage properties of CBT thin films were systematically studied by X-ray diffractometer,field emission scanning electron microscope,ferroelectric analyzer and impedance analyzer.The results show that the prepared films all exhibit a polycrystalline bismuth layered structure without other phase formation.The addition of BFMT into thin film obviously enhances the maximum polarization strength Pm and breakdown field strength Eb,reduces the leakage current density.With the increase of BFMT solid solution,the breakdown field strength Eb of CBT-xBFMT film increases first and then decreases,and reaches the maximum value at x=0.10.The maximum polarization strength Pm gradually increases,and the largest polarization strength difference is obtained at x=0.10.The largest polarization intensity difference and breakdown field strength make CBT-0.10BFMT film has the best energy storage properties.The recoverable energy storage density Wrec and energy storage efficiency η of CBT-0.10BFMT film are up to 82.8 J/cm3 and 78.3％,respectively.And its energy storage characteristic has good temperature stability in the temperature range of 25～150 ℃.Therefore,CBT-0.10BFMT ferroelectric film is expected to be used in environmentally friendly micro energy storage devices.关键词
