摘要

在采用镧锶钴氧化物上下电极的PLZT薄膜电容器上测量了铁电压印。数据显示，在温度升高和交变(单极)电压应力的联合作用下，印痕显著增加。在没有外部偏压的温度应力样品上没有观察到印记。

Imprint of ferroelectric PLZT thin-film capacitors with lanthanum strontium cobalt oxide electrodes

The ferroelectric imprint is measured on thin-film PLZT capacitors with lanthanum strontium cobalt oxide top and bottom electrodes. The data show a significant amount of imprint with a combined elevated temperature and alternating (unipolar) voltage stress. No imprint was observed on samples that were temperature stressed without external bias.
