The parameter dependence of vacancy and self-interstitial formation energies has been studied with an analytic nearest-neighbor atomistic model based on the embedded-atom method. The model was designed for fcc copper, but the results should not depend on either the structure or the element. Exponentially decreasing functions were used for both the electron density function and the two-body interaction. Energies were dependent on the cutoff procedure for these functions between first and second… CONTINUE READING
