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。
The segregation of S and O on the V (100) surface has been studied in detail by means of surface analysis such as AES and LEED. The relationship between segregation of S and O was clarified. Two new surface structures (8 × 1) -O and (4 × 1) -O were found. The surface V (100) surface was systematically observed and analyzed under different S and O segregation The various superficial structures of the surface and the interrelationships of these superficial structures are obtained.
