摘要：
Several models, free of any adjustable parameters, for the size-dependent melting temperature and the size-dependent lattice contraction of nanocrystals and related solid-liquid interface energy are introduced and compared with the newest experimental results of Bi nanocrystals. It is found that the models may interpret the experimental results well. (C) 2003 Elsevier Science B.V. All rights reserved.
