Metastability of multitwinned Ag nanorods: Molecular dynamics study

Nanoscale rods have been shown to exhibit a multiple twinned structure. The rods grow along a [110]-type crystallographic direction and have a pentagonal cross section with five (111) twins connecting the wire center to the corners of the pentagon. Here, we use molecular dynamics simulations with an embedded atom method interatomic potential for Ag to compute the ground-state energies of the multitwinned rods and compare with the bulk …
