摘要：

Iron films deposited by magnetron sputtering on glass substrates were converted into FeS2 films by sulfidation during isothermal annealing at 400 degrees C. The formation of FeS2 microcrystalline has been investigated under different annealing times. The conversion of Fe --> FeS2 may occur during annealing for 1 h. The grain size and the amount of FeS2 phase significantly increase with the annealing time. However, the crystallization rate indicates an insignificant rise when the annealing time is longer than 10 h. The iron films can be substantially converted into FeS2 thin films which have an approximate stoichiometric composition under the condition of sulfidation annealing from 20 h to 30 h.
