| 摘 要： | 介绍了用偏光显微镜对α-LiIO3特性的观察.研究了五种不同电极界面状态的八块晶体样品在c向静电场作用下晶体的电导、空间电荷的沉积和分布.观察到由于α-LiIO3的空间电荷的输运形成的彩色准直条纹.此彩色条纹与光折变型光栅的衍射带之间有对应关系.而不同的电极界面状态对α-LiIO3晶体的电导和离子输运有明显的影响.

| Abstract: | This paper presents an account of our observation on characters of the α-LiIO3 by using a plorazation microscope. The conduction of crystal,the deposition and distribution of the space charges were studied for eight crystal specimens under the actions of the DC electric field in c-direction with five different electrode interface states. The colored quasi-straight bright lines were observed that formed through the transport of the space electric charges of α-LiIO3.There are a correspondence relation between it and the diffraction band of the photo-refractive grating in the crystals, and the different interface states have exerted obvious influence on the ionic transport and crystal conduction in α-LiIO3. |
