摘要: A sound knowledge and understanding of the thermal stability nanowires is a prerequisite for reliable implementation nanowire-based devices. We investigate morphology Au annealed isothermally at different temperatures. During processes, triggered by heating, wires undergo various configurational changes to finally break up into chains nanospheres much lower than bulk melting temperatures due capillary or so-called Rayleigh instability. The role three parameters, namely, wire diameter, temperature, annealing time, on final investigated. Both average sphere diameter mean spacing between adjacent spheres are larger values predicted materials with isotropic surface energy. Possible reasons discussed in paper.
