用溶胶-凝胶法在Pt/Ti/SiO2/Si(001)基片上制备了BiFe0.95Mn0.05O3/Pb(Zr0.4Ti0.6)O3/BiFe0.05O3(BFMO/PZT/BFMO)集成薄膜,采用X射线衍射仪分析了其物相结构;采用铁电测试仪考察了该集成薄膜与铂极构成的铁电电容器的性能.结果表明:该集成薄膜结晶较好,除BFMO、PZT及基片的衍射峰外没有其它衍射峰存在;当电场强度为0.7 MV·cm-1时,Pt/BFMO/PZT/BFMO/Pt电容器的电滞回线对称性良好,剩余极化强度为17.9μC·cm-2,矫顽力为0.12 MV·cm-1;在电场强度为0.4 MV·cm-1下测得的铁电电容器漏电流密度为2×10-5A·cm-2,电容器在经过1010次反转后未出现明显的疲劳现象.
