| 英文摘要 | The melting properties of free nanoclusters of silver atoms interacting through an analytic embedded-atom method type potential are studied by using molecular dynamics simulations. The particle-size-dependent depression of the melting temperature T-m of Ag258-3871 can be explained by the surface premelting models (SPM). The melting process of Ag-13 (178) changes significantly compare with that of Ag258-3871, in which T-m deviate from the values predicted from the SPM and the latent heat of fusion Delta mu (ls) enhance greatly. For the first time, the size-dependent variations in T-m and A mu (ls) for free neutral nanoclusters with r less than or equal to r(c) (r(c) is critical radius) is presented and a new intermediate melting mechanism is identified. In addition, a reentrant morphology transition in Ag-147, quasimelten phases of Ag13-55, and icosahedral precursors to the melting of Ag13-309 are also recovered. |
