In this letter, the melting behavior of nickel nanowire is reported. The curves of the atomic volume, internal energy, and the local cluster are used to monitor the phase transition. We show that upon heating the nanowires undergo a coexistence of crystal and liquid units in the melting process of the nanowire. The thermal stability of nickel nanowires is dependent on the structures and size of the nanowire. The melting is not only due to the single atom's diffusion, but also the diffusion of the local clusters. (C) 2005 American Institute of Physics.

Abstract
In this letter, the melting behavior of nickel nanowire is reported. The curves of the atomic volume, internal energy, and the local cluster are used to monitor the phase transition. We show that upon heating the nanowires undergo a coexistence of crystal and liquid units in the melting process of the nanowire. The thermal stability of nickel nanowires is dependent on the structures and size of the nanowire. The melting is not only due to the single atom's diffusion, but also the diffusion of the local clusters. (C) 2005 American Institute of Physics.File in questo prodotto:
