Abstract

The stability analysis of elliptical metal nanowires, using a jellium model, was presented. It was shown that a Jahn-Teller deformation breaking cylindrical symmetry can be energetically favorable, leading to stable nanowires with elliptic cross sections. It was found that the derived sequence of stable cylindrical and elliptical geometries explains the experimentally observed shell and superstructures for alkali metals. It was suggested that for gold, elliptical nanowires are even more likely to form since their eccentricity is smaller than for alkali metals.
