摘要：

A model, free of any adjustable parameter, has been developed for the size-dependent melting temperature and melting entropy of nanocrystals. The model can be utilized to predict the thermal stability both for metallic and organic low dimensional materials. The results show that their melting thermodynamic functions are dependent on their size, dimension, and environment. The theoretical predictions in terms of the above model are fully consistent with experimental evidences and the results of molecular dynamics simulation. (C) 2000 Elsevier Science S.A.
