A Simulation of Dielectric Spectroscopy of Some Ferroelectric Materials

Abstract

Temperature dependent dielectric permittivity is a crucial parameter in determining the physical property of ferroelectric materials. A method of using temperature to predict the dielectric permittivity of some ferroelectric materials is studied. The object of this work is to search for the applicable method of using temperature to predict the dielectric permittivity and control the transition of some ferroelectric materials from ferroelectric phase to paraelectric phase. A typical numerical method is highlighted and discussed in light of the potential applications to the various experimental results. The simulations agree very well with the observed spectroscopy of twelve curves for dielectric permittivity versus temperature. The minimum value of correlation coefficients between actual and calculated data is 0.98. The maximum data of mean relative errors is 6.98%. This study may make a contribution to the theoretical and the practical aspects of the ferroelectric materials.
