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.
