Abstract

A simple method is proposed for calculating the spatial extensions of wave functions in a tightbinding system. By means of the cluster Green functions, site-coefficients (amplitudes of the Wannier functions) of central sites in various type clusters within the system are derived, and the structures of the wavefunctions are discussed. As an example, the theoretical results for a ternary alloy are obtained and compared with the results from exact calculation of the 300-site model.
