Modeling of the dielectric and hysteresis properties
Dausch, D. E., Furman, E., Wang, F., & Haertling, G. H. (1996). PLZT-based multilayer composite thin films, Part II: Modeling of the dielectric and hysteresis properties. Ferroelectrics, 177(3-4), 237-253. https://doi.org/10.1080/00150199608223632
PLZT-based composite thin films with various compositions were fabricated and characterized in Part I of this study. Similarly to procedures reported in the literature, the low-field dielectric properties in Part II were modeled according to a series capacitor model based on the dielectric constants of the individual composite constituents. In order to model the FE high-field switching properties, AFE-to-FE phase transitions and non-uniform electric field distributions in the composite films, a new hysteresis modeling technique was developed based on a series capacitor model featuring the nonlinear polarizabilities of the individual components as evident from experimental data. The model predicts the behavior of any composite film structure provided the pure component properties are known.
