In this paper a growth recipe for well-ordered iron sulfide films and the results of their characterisationare presented. The film was studied using X-ray diffraction (XRD), X-ray photoelectron spectroscopy(XPS), low energy electron diffraction (LEED), and scanning tunneling microscopy (STM). XRD data revealthat the film has a NiAs-like structure with Fe vacancies, similar to iron sulfides such as pyrrhotite andsmythite, although no indication of any ordering of these vacancies was observed. LEED and STM resultsshow that the film exhibits a 22 surface reconstruction. XPS data provide additional evidence for alarge number of Fe vacancies, and the oxidation states of the Fe and S in the film are analysed.
