Melting behavior in ultrathin metallic nanowires
PHYSICAL REVIEW B 66, 085408 (2002),-0001,():
The thermal stability of helical multiwalled cylindrical gold nanowires is studied using molecular-dynamics simulations. From our simulation, the melting temperature of gold nanowires is lower than the bulk value, but higher than that of gold nanoclusters. It is interesting to find that the interior melting temperature in ultrathin nanowires is lower than that of the surface melting. The melting starts from the interior atoms, while the surface melting occurs at relatively higher temperature. This unique thermodynamic behavior is closely related to the interior structures. We propose that the surface melting represents the overall melting in ultrathin metallic nanowires.
