Computer simulations suggest that ultrathin metal wires should developexotic, non-crystalline stable atomic structures, once their diameter decreasesbelow a critical size of the order of a few atomic spacings. The newstructures, whose details depend upon the material and the wire thickness, maybe dominated by icosahedral packings. Helical, spiral-structured wires withmulti-atom pitches are also predicted. The phenomenon, analogous to theappearance of icosahedral and other non-crystalline shapes in small clusters,can be rationalized in terms of surface energy anisotropy and optimal packing.Comment: 5 pages, 2 figures, REVTe
