Initial stages of formation of platinum (Pt) silicide have been studied by ultrahigh vacuum scanning tunneling microscopy (UHV-STM). Stranski-Krastanov growth mode has been observed for the Pt silicide. Layer-by-layer growth occurs at submonolayer coverages resulting in four different surface structures. At coverages more than one monolayer (ML) Pt silicide islands start to nucleate. The morphology of the silicide is represented by separated islands or very long nanowires depending on preparation technique. The islands are supposed to grow endotaxially with a large top facet corresponding to PtSi(101) surface.
