摘要
采用溶胶-凝胶法在LaNiO_3/Si(100)底电极上成功制备了Zr/Ti摩尔比不同的Pb_(0.88)La_(0.08)(Zr)xTi_(1-x))O_3(x=0.30,0.55,0.80)的厚膜,研究了Zr/Ti摩尔比对PLZT反铁电厚膜的结构与储能行为的影响。结果表明:Zr/Ti摩尔比对PLZT反铁电厚膜的结构无太大影响;随着锆钛比中锆含量的增加,储能密度和储能效率呈现逐渐增加的趋势,其中PLZT(8/80/20)厚膜在电场强度为1400kV/cm时储能密度达到最大,为23.8J/cm^3,储能效率高达60.0%。
The different different zirconium content in Pb0.88La0.08（ZrxTi1-x）O3（x=0.30,055,0.80）（abbreviated as PLZT） thick films with 1μm thickness were successfully fabricated on LaNiO3/Si（100） by the sol-gel method. The effect of different zirconium content of the PLZT anti-ferroelectric thick films on the dielectric and energy-storage properties were studied scientifically. The results show that the structure of the PLZT anti-ferroelectric thick films was not affected, after zirconium content performance enhanced significantly, when ratio is （8/80/20）, the energy-storage density （W） and energy-storage efficiency （η） were increased, and the maximum W=23.8J/cm^3 and corresponding η=60% were obtained from the PLZT（8/80/20） thick films at 1400 kV/cm.
