This book is the proceedings of the Sixth Battelle Colloquium on the Science of Materials. The Colloquium was devoted to a new field of materials science in which computers are used to conduct the experiments. Although the computer methods used have reached a high degree of sophistication, the underlying principles are relatively straightforward and well understood. The interatomic force laws - a vital input into these computations - however are less well understood.

Abstract: Availability of a reliable interatomic potential is one of the major challenges in utilizing molecular dynamics (MD) for simulations of metals at near the melting temperatures and melting point (MP). To enable molecular dynamics simulations of high-energy collisions, it is common practice to use a screened Coulomb force field to describe the interactions and to smoothly join this to the equilibrium force field at a suitable interatomic spacing.

For the calculation of interatomic potential by Gaussian’XX, the interatomic distance and .

For the calculation of interatomic potential by Gaussian’XX, the interatomic distance and bases sets of electron wave function for the two atoms are required. Several grades of the bases sets are chosen only by giving atomic numbers Z of the elements concerned when Z<18. As noted earlier, lattice energy minimisation methods may be readily applied to surfaces for which the Ewald summation has been adapted to two-dimensional periodic boundary conditions. Calculations on defects and impurities can also be performed using periodic methods (employing supercells, in which the defect is embedded).

Interatomic potentials for simulation of quasicrystal and its approximant. It is the most widely used interaction in the simulation of simple systems. The other kind is Realistic potentials represented by Moriarty-Widom potential and potentials from Force Match method. These potentials are based on the first principle and experimental results, which plays an important role in the simulation of alloy systems such as AlNiCo.

Preceding chapters of this volume show significant progress in developing bulk potentials; how-ever, very few interatomic potential models are designed particularly for application to surfaces. Therefore, surface simulations have been confined largely to the summation of pairwise interatomic potentials (SPP) tech-nique.
