Preparation of BiFeO_3/Bi_4Ti_3O_(12) multilayer with Sol-gel Method and Its Electric Properties

Hongri Liu

Abstract

BiFeO3 / Bi4Ti3O12 multilayer film was prepared on FTO/glass bottom electrodes by sol-gel process. Structure, ferroelectric and Dielectric properties at room temperature were studied by comparing with pure BiFeO3 film. BiFeO3 and Bi4Ti3O12 phase can be identified from the XRD pattern. Comparing with pure BiFeO3 film, the BiFeO3 /Bi4Ti3O12 and Bi4Ti3O12/BiFeO3 multilayer film can endure higher applied field and thus getting fully polarization and show more intense ferroelectricity, Under an applied field of 450 kV/ cm ,the remnant polarizations are 37μC/ cm2 and 23μC/ cm2 , respectively.
