摘要：

A simple procedure for the production of pyrite (FeS2) thin films starting from the pure elements is presented. A pure, highly (110) oriented polycrystalline iron precursor layer could be successfully electro-deposited. Direct sulphurization of those films on Mo foils resulted in pyrite with (200) oriented grains embedded in a randomly oriented matrix. No other iron sulphide phase like e.g. marcasite was observed. XPS shows the presence of at least 97% FeS2. Depth profiles demonstrate the stoichiometric homogeneity across the films.
