摘要：
By considering the surface effects, the melting temperature of nanosolids (nanoparticles, nanowires and nanofilms) has been predicted based on size-dependent cohesive energy. It is shown that the melting temperature of free standing nanosolids decreases with decrease in the solid size, and the melting temperature variation for spherical nanoparticle, nanowire and nanofilm of a material in the same size is 3:2:1. The present theoretical results on Sri and Pb nanoparticles, In nanowires and nanofilms are consistent with the previous experimental values. (c) 2005 Elsevier B.V. All rights reserved.
