Stable Nanobridge Formation in <110> Bold Nanowires Under Tensile Deformation

H. S. Park and J. A. Zimmerman, Scripta Materialia, 54, 1127-1132 (2006).

We present atomistic simulations of < 110 > oriented gold nanowires under tensile deformation. We find that < 110 > gold nanowires tend to form elongated, stable nanobridges upon necking, which is in agreement with previous experimental observations. In addition, the simulations reveal that the formation of a high strength multishell lattice structure during the plastic deformation of the < 110 > wires may account for the stability of the elongated nanobridges observed experimentally.
