摘要

基于Devonshire理论,发现两个热力学参数的比值,即极化温度系数,是热释电和介电可调性效应的关键。比值越小,介电峰位移越大,电激极化越大。该材料将具有更高的温度稳定介电可调性,适用于微波器件。从居里点开始,随着温度的降低,电滞回线形状和尺寸的变化越大。材料将具有较大的热释电系数。导出了热释电系数除以介电常数平方根为常数的实验定律。

Effects of electric field induced polarization on dielectric tunability and pyroelectric coefficient
ABSTRACT Based on the Devonshire theory, a ratio of two thermodynamic parameters, a polarization – temperature coefficient, is found as the crucial for pyroelectric and dielectric tunability effects. Smaller ratio corresponds to larger degree of shift of dielectric peak and larger E-induced polarization. The materials will have higher temperature-stable dielectric tunability suitable for microwave devices. Larger ratio corresponds to larger change of electric hysteresis loop in shape and size with decreasing temperature from the Curie point. The materials will have larger pyroelectric coefficient. An experimental law that pyroelectric coefficient over square root of dielectric constant is a constant is derived.

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.
