摘要
In order to understand the structure and properties of cylindrical ultrathin copper nanowires, we have simulated the growth of cylindrical copper nanowires using the steepest descent method, and investigated the energy per atom from changing the diameter, from spreading sheets, from the angular correlation function, and from the radial distribution function. The stable structure of the cylindrical ultrathin copper nanowires was found to be multi-shell packs composed of coaxial cylindrical shells with a {111) facet. As the diameter of the nanowire increases, the structural properties of nanowire becomes close to those of the bulk.
