Formation of pyrite (FeS 2) films through electrodeposition from aqueous solutions which contain different source materials has been investigated. Na 2S 2O 3·5H 2O is used as sulfur source material, FeSO 4·7H 2O, FeCl 2·4H 2O and FeCl 3·6H 2O are used as iron source materials respectively. The samples are annealed in N 2 atmosphere at 400 ℃ and 500 ℃ respectively. From XRD (X-ray diffraction) patterns of the films, it is found that there are peaks of FeS 2, FeS and Fe 7S 8 in all films, but there are sharp and more peaks characterizing FeS 2 in the film from Na 2S 2O 3 +FeSO 4 than other films, and 400 ℃ is the more suitable temperature than 500 ℃ for annealing the samples in N 2 atmosphere. In addition, one solution can be used repeatedly. 展开更多

The preparation methods of simultaneous electro deposition for pyrite (FeS 2) thin film are introduced from aqueous solution of FeSO 4 and Na 2S 2O 3. Electrical process is studied in detail in the paper. From the experiment result, the best way of drying the sample is to dry it in vacuum. Electro deposition method for the preparation of pyrite thin film is a safe, simple and low cost method. 展开更多
