Abstract

Silicon nanowires, with the 〈100〉 and 〈110〉 growth directions and at several surface facet configurations, were investigated by molecular dynamics simulations. We considered three commonly used interatomic potentials for silicon, and tested the reliability of each model to describe silicon nanowires. We find that, for each growth direction, the facet family plays a central role on the nanowire energy, which follows a universal scaling law as a function of the nanowire perimeter. Those results were discussed in the context of recent experimental and ab initio data. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
