摘要: 用AES,LEED等表面分析手段,对V(100)表面上杂质S,O偏析作了详细研究。明确了S,O偏析关系;发现(8×1)-O,(4×1)-O两个新的表面结构;系统观察和分析了V(100)表面在不同S,O偏析量情况下的各种表面超结构,并获得这些表面超结构的相互关系。

Abstract: The sulphur and oxygen segregation on V(100) surface is investigated in detail by AES and LEED. The relation between S and O segregation is clearly demonstrated and two new surface reconstructions, (8×1)-O and (4×l)-O,on V(100) surface are disclosed. Various superstructures on this surface under different conditions of S & O segregation are studied systematically and the relationship among these surface structures is obtained.
