晶体及超晶格中的压电场分布

更新时间：2026-09-14

本文纠正了教科书上只有压电效应时关于Ｅ，Ｐ，Ｄ之间关系的一个错误，并从麦克斯韦方程组出发，讨论了一般情况下受有应力（应变）作用的平板晶体及超晶格中的压电场分布，绘制了晶体的纵横尺寸比取不同值时的压电场图

This paper corrected a mistake of some textbooks about the relation of E

D and P when only piezoelectricity exist

and discussed piezoelectric field distribution in crystals and strained superlattices under general condition according to Maxell′ equations

and piezoelectric field figures were drawn. When length/width of a crystal has different proportion.
