Effective interaction energy among nitrogen atoms on Cu(100)‐ c (2 × 2)N surface was obtained by a density functional plane‐wave pseudopotential calculation. For efficient calculation of metallic systems, a preconditioning method for the local potential in self‐consistent field iteration was proposed. Attractive interaction energy among nitrogen atoms consistent with a high‐temperature STM experiment was obtained. © 2002 Wiley Periodicals, Inc. Int J Quantum Chem, 2003
