LB膜作为模板可调控晶体的取向生长。实验中利用 SEM,XRD等手段研究了转移到硅基底上的 L B膜诱导氟化钙单晶的生长情况。发现 :在二十二烷基羧酸 L B膜诱导下 ,氟化钙晶体沿(2 2 0 )晶面取向生长 ,这一结果可利用膜与晶体之间的晶格匹配关系得到合理解释
LB film as a template can control the crystal orientation growth. In the experiment, the growth of calcium fluoride single crystal induced by L B membrane transferred to the silicon substrate was studied by means of SEM and XRD. It was found that the calcium fluoride crystal grows along the (200) crystal plane induced by BSA film, and this result can be reasonably explained by the lattice matching between the film and the crystal
