Research on the Intrinsic Correlation Between the Polarization Offset and Pyroelectric Properties of Temperature-Gradient Ferroelectric Materials
In the theoretical framework of mean field approximation,the extended theory of the transverse ising model is adopted to explore the microscopic physical mechanism of the intrinsic correlation between the polariza-tion offset and pyroelectric properties of temperature-gradient ferroelectric materials.Research results show that the extreme value of polarization offset is closely related to the properties of the initial phase-transition gradient layer in materials.The extreme value of polarization offset and the peak value of pyroelectric coefficient always appear in pairs,and altering the properties of the initial phase-transition layer in temperature-gradient ferroelectric materials is a key factor in regulating polarization offset and improving the pyroelectric performance of materials.
