Abstract

An Embedded Atom Method Model for graphite has been derived based on a short-range Morse two-body potential and an electron density function with both radial and angular terms. This part of the model involves interaction only within a hexagonal plane, and the interaction between planes is approximated by a Buckingham potential. The model is stable with respect to fcc, bcc, and diamond structures. The effective two-body potential is very small, indicating that defect properties are dominated by the noncentral many-body interactions.
