One-dimensional atomic systems modelling nickel nanowires are constructed on the base of icosahedral structural motif. The structure evolution of icosahedral nanoparticles and nanowires with temperature is examined by molecular dynamics simulations as a function of their shape and size. The drastic change of regular solid shape (shape transformation) detected in Ni icosahedral nanowires is interpreted as a specific type of solid state transformation in one-dimensional system that is controlled by surface diffusion.
Key words: nanowire, nanoparticle, icosahedron, one-dimensional system, melting temperature, Rayleigh instability, surface diffusion.
