Abstract

Electrodeposition of iron and sulfur from an aqueous solution was studied as a method for pyrite (FeS 2) thin-film preparation. By using FeSO 4 and Na 2S 2O 3 as source materials, co-deposition of iron and sulfur was attained. Although the S/Fe ratio in deposited films were ∼1, stoichiometric pyrite thin films were successfully formed by the post annealing at around 500°C in a sulfur atmosphere.
