LB膜诱导CaF_2单晶的生长研究

Study of the Growth of CaF_2 Single Crystals under LB Films

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 。

Control over crystallization can be achieved by means of LB films.In this paper,the oriented growth of the CaF 2 single crystal on the silicon wafer with LB monolayer was investigated through a series of technology such as SEM,XRD.The results show that CaF 2 crystal on the (220) axis under benhenic acid monolayer,which can be rationalized in term of the lattice match between monolayer and crystal.
