Abstract :
Based on the modified Ginzburg-Landau-Devonshire theory, the behavior of a ferroelectric film consisting of two different materials with an interface parallel to the spontaneous polarization is studied. The results show that for the composite ferroelectric film properties (transformation temperature, pyroelectric coefficient, etc), the Curie-temperature difference between two bulk materials is sensitive influencing factor and the change of the thickness of the transition layer has little influence.
