Abstract
Pyrite (FeS2) thin films have been prepared by direct H2S gas chalcoge nization of electrodeposited iron thin films at temperatures ranging f rom 300 to 500 degrees C. Polycrystalline films with grain sizes of up to 0.9 mu m were achieved. A reaction model is developed. It suggests that the surface coverage of adsorbed atomic sulphur determines the m echanism.
