Abstract
A unified model, free of any adjustable parameters, for the size-dependence and dimension-dependence of melting point depression and superheating of n anocrystals is developed. In terms of the consideration of the surface/volu me ratio of nanocrystals, the suppression of melting point of nanocrystals and superheating of embedded nanocrystals are predicted. The model predicti ons for the melting temperatures of nanocrystals are consistent with the ex perimental results and molecular dynamics simulations.
