Fe layers prepared by magnetron sputtering on Si(100) substrates have been sulfurized thermally to form FeS
2
thin films at different temperatures (200—400℃) for 10 hours. The structural and surface properties of FeS
2
have been studied. The results of XPS have shown that sulphur would exist at low temperature. When the iron film is sulfurized at high temperature
sulphur would change into pyrite
but small amount of sulphur would still remain on top of the film. The ratio of iron to sulphur is very close to its stoichiometric proportion according to RBS spectrum at 400℃.
