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 .
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 .
