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。

By using finite element ( FE) method and considering the stochastic dependence of the discharge growth probability on the local electric field, the discharge pattern and fractal dimension were obtained with calculation of distribution of electric field in system of needle-plate electrode by computer. 采用有限元法计算了针-平板电极系统的电场分布,考虑放电生长几率与局部电场的随机关系,计算机模拟出放电图形。借此求得分形维数。
On the other hand, screening effect sharply lowers the local electric field at the nanowire tips when the density is too high. 另一方面,过大的密度带来的屏蔽效应将严重削弱纳米线尖端的局域电场。
