Long, straight self-assembled nanolines of Bismuth are used as an atomic-scale non-lithographic template for the deposition of different metals. The Bi nanolines are 15 Å wide and can grow to lengths exceeding 1μm, limited only by the substrate terraces. We describe the method of formation of these templates, and demonstrate strongly preferential adsorption of different metals. We observe both wetting behaviour, in which elongated metal islands form nanowires along the template, and nonwetting behaviour, in which arrays of metal clusters of uniform size are produced.
