Query: Multishelled Gold Nanowires   The current miniaturization of electronic devices raises many questions about
the properties of various materials at nanometre-scales. Recent molecular
dynamics computer simulations have shown that small finite nanowires of gold
exist as multishelled structures of lasting stability. These classical
simulations are based on a well-tested embedded atom potential. Molecular
dynamics simulation studies of metallic nanowires should help in developing
methods for their fabrication, such as electron-beam litography and scanning
tunneling microscopy.
