Abstract

A method for calculating the thermodynamic properties of both perfect crystals and defects from a single zero-temperature energy minimization is described. The validity of the method is demonstrated by determining the free energy and the lattice parameter of a perfect Au crystal, as modelled by an embedded-atom method (EAM) potential. In addition, we determine the temperature dependence of the vacancy formation energy and the excess free energy of a (100) free surface.
