| 摘 要： | 利用磁控溅射产生金属Ｃｕ团簇，同时蒸发ＣａＦ２介质，将Ｃｕ团簇包埋在ＣａＦ２介质中，团簇大小可通过改变溅射气压控制，用ＴＥＭ研究了嵌埋团簇的结构，分析结果表明：Ｃｕ团簇呈三角状多晶结构，团簇大小为１０￣７０ｎｍ，基质ＣａＦ２晶体也为多晶结构，Ｃｕ团簇的晶格常数在包埋状态下发生了膨胀，膨胀率大约在１６％左右。

| Abstract: | By using magnetic controlled sputter and evaporation device Cu clusters embedded in CaF_2,have been successfully prepared.TEM is used in studying the micro structures.The results show that the copper cluster is well embedded in CaF_2 and the size of the triangle-shaped grains,Cu clusters,is from 10nm to 70nm.The Cu cluster and medium CaF_2 are both polycrystalline structure,and the Cu cluster's lattice constant expands about 16%. |
