Fabrication and research of periodically poled lithium niobate structure .

周期性极化反转铌酸锂之结构制作与研究。

We studied the mechanism of the visible light-induced domain switching in the lithium niobate crystals , and considered that the main factor is the movement of light-induced carrier , which modified the local electric field in the crystals and then resulted in the reduction of the domain switching voltage .

探寻了可见光诱导铌酸锂晶体畴反转的形成机制，认为光诱导晶体畴反转的主要原因是光激载流子迁移改变了晶体内部的局域电场，造成了晶体极化反转电压的降低。

With developing fleetly in the modern science and technology and strengthening the consciousness of environmental protection , to develop lead-free piezoelectric niobate ceramics with high temperature and fine performance has become the hotspot of the current research .

随着现代科学技术的飞速发展和人类环保意识的加强，具有优良性能的高居里温度的铌酸盐系无铅压电陶瓷已成为当前研究的热点。
