摘要：

A review of a thermodynamic model of polarization-graded ferroelectrics is presented. Using this formalism, the unusual dielectric and pyroelectric properties of compositionally graded ferroelectric films are analyzed. Results show that the "strength" of the grading can be chosen as a design parameter to achieve desirable dielectric and pyroelectric responses.
