Abstract—

In this paper, we describe improved methods for assessing the static and dynamic piezoelectric properties of lithium niobate crystals. The results can be used for evaluating results of conversion of large lithium niobate crystals to a single-domain state under mass production conditions. We present main calculated relationships for assessing the degree of unipolarity and the relative volume of antiparallel domains in large lithium niobate crystals. The described techniques are applicable to other piezoelectric materials as well.

使用静态和动态压电测量估算LiNbO 3晶体的单极性程度

摘要-

在本文中，我们描述了评估铌酸锂晶体静态和动态压电特性的改进方法。该结果可用于评估大规模生产条件下大铌酸锂晶体向单畴态转化的结果。我们目前主要的计算关系，用于评估铌酸锂大型晶体中单极性程度和反平行域的相对体积。所描述的技术也适用于其他压电材料。
