摘要 用sol-gel法成功制备了Bi3.15Nd0.85Ti3O12铁电薄膜,XRD结果表明制备的BNT薄膜具有(117)和(00l)的混合取向,FE-SEM显示薄膜表面光滑致密,颗粒均匀。剩余极化Pr和矫顽场Ec分别为29.5μC/cm2和100kV/cm,经过109次循环后几乎无疲劳。 Bi3.15Nd0.88Ti3O12 （BNT） thin film was fabricated by sol-gel method. X-ray diffraction pattern showed that the BNT thin film exhibited a highly random orientation with predominantly （117） and （00l） orientation. FE-SEM showed that the BNT thin film had a dense and homogeneous microstructure without any crack. The Pr and Ec values of BNT thin film were 29.5μ℃/cm^2 and 100kV/cm,respectively. The fatigue test exhibits a very strong fatigue endurance up to 10^9 cycles.
