摘要

系统地研究了直流电压下PIN-PMN-PT四边形单晶的介电和压电性能。随着直流电压(0~2000V)的升高，介电常数和压电系数减小，介电损耗基本保持不变。虽然直流电压确保单晶不会去极化，但需要在施加的电压和单晶的电学特性之间找到平衡。

Electrical Properties of Tetragonal PIN-PMN-PT Single Crystal under DC Voltage

The dielectric and piezoelectric properties of tetragonal PIN-PMN-PT single crystal under dc voltage have been systematically investigated. The dielectric constant and piezoelectric coefficient decreased, and dielectric loss remained basically invariable with increasing of the dc voltage(0~2000V). Although the dc voltage ensures the single crystal is not depolarized, a balance need to be found between the applied voltage and the electrical properties of the single crystal.
