摘要：
A model for the equilibrium transition size and temperature between nanodiamond and nanographite was established in terms of the effect of surface stress on the internal pressure of nanocrystals. It was found that as size and temperature decreased, the relative stability of diamond in comparison with graphite increased. The obtained result is consistent with other theoretical and experimental results. (C) 2002 Elsevier Science B.V. All rights reserved.
