Size effect on thermodynamic properties of free nanocrystals
arXiv:0808.3487 · doi:10.1140/epjb/e2008-00429-9
Abstract
We demonstrate that the discrete character of the vibrational spectrum of a small crystal accounts for size dependence of its thermodynamic properties and melting temperature. Using a self-consistent statistical method [Phys. Rev.B 66, 054302 (2002)] we derive the Gibbs free energy of free nanocrystalline plates and calculate the thermodynamic parameters as functions of plate thickness for Cu.
