“Background Iron silicides grown on silicon surfaces have attracted much attention in the last decade because of their possible applications in different technological areas [1–4]. The equilibrium Fe-Si phase diagram shows that there exist four stable bulk compounds: Fe3Si crystallizing in cubic D03 structure, simple cubic ϵ-FeSi, tetragonal α-FeSi2, and orthorhombic β-FeSi2[5].These iron silicides exhibit metallic, semiconductor, or insulating behavior depending on their structures. For example, Fe3Si is ferromagnetic and is a promising candidate as spin injectors in future spintronic devices such as magnetic tunnel junctions [6]. β-FeSi2 is semiconducting with a direct band gap of approximately 0.85 eV, which fits into the window of maximum transmission of optical fibers and is expected to be a suitable material for optoelectronic devices such as light detectors or near-infrared sources [2, 7].
