CEMS方法是近几年来发展起来的用于测量薄膜材料微观化学信息,如化学键态,近邻配位情况等的新手段。将该方法与离子辐照固体表面的研究结合起来,以丰富人们有关固体材料的“辐照效应”的知识是一个有意义的探索。SnO_2和Fe_2O_3不仅是含穆斯堡尔元素的材料而且又在矿物学上分别代表两大类矿物结构,即Rutil和Wuslile结构。在离子辐照下将会引起化学键的断裂,使结构发生改变。而CEMS方法对研究这一现象是十分有效的。
CEMS method is a new method developed in recent years for measuring the microscopic chemical information of thin film materials, such as the chemical bond state, the coordination situation of neighboring neighbors and so on. The combination of this method with the study of ionically irradiated solid surfaces to enrich people’s knowledge of the “radiation effect” of solid materials is a meaningful exploration. SnO 2 and Fe 2 O 3 are not only the materials containing Münsburg elements but also represent the mineralogical structures of two major categories, Rutil and Wuslile respectively. In the ion irradiation will cause the chemical bond fracture, the structure changes. The CEMS method to study this phenomenon is very effective.
