Abstract
The great power of the cluster-expansion method for atomistic simulations of the ground state properties and the thermodynamic properties of multi-component solids is highlighted. In the first part of the paper some recently developed combinations of this method with other atomistic simulation techniques (N-body potentials and cluster functionals) are discussed. In the second part the ab-initio cluster expansion method is used to investigate the ground-state structures for bulk FexCo1-x, the Ni90%-Al(110) surface and for adatom configurations on Mo(112), and the phase diagram for the system Ni-Fe-Al. Finally, an outlook for future applications of this calculational technique is given. (c) 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
