Abstract
ABSTRACT In this paper, a very simple methodology to characterize the polarization of ferroelectrics via electrical field is proposed. This methodology allows us to use not only experimental electrical field-polarization curve as classical models do, but also physical status of ferroelectrics. The methodology is based on the use of Fermi-Dirac distribution, from eight measured P–E curves of two ferroelectrics materials, the theoretical polarization-electrical field curve repeat experimental path very well. Meanwhile, the effects of physical status on ferroelectric hysteresis loop are explained through mathematical route.
期刊介绍:
Ferroelectrics Letters is a separately published section of the international journal Ferroelectrics. Both sections publish theoretical, experimental and applied papers on ferroelectrics and related materials, including ferroelastics, ferroelectric ferromagnetics, electrooptics, piezoelectrics, pyroelectrics, nonlinear dielectrics, polymers and liquid crystals.
Ferroelectrics Letters permits the rapid publication of important, quality, short original papers on the theory, synthesis, properties and applications of ferroelectrics and related materials.
