Influence of Size on the Melting Temperature of Metallic Nanoparticle

   In This paper, the effect of size on melting temperature of metallic nanoparticles (Au, Pb and Bi) is theoretically simulated and explained. In this regard, the cause of difference in various experimental data is introduced, which is the difference between nanoparticles’ grain Gaussian distribution. This volume-depended model with the help of the Gaussian distribution can describe the relation between nanoparticle melting temperature and its size. The obtained results are interestingly consistent with reported experimental data.
