Аннотация:We have developed a set of two-body and three-body potentials for modeling the structure of solid phases of germanium. The potential is of the same functional form as that of Stillinger and Weber for silicon, but it has different values of the parameters. The potential gives an excellent structural representation of amorphous solid Ge as well as crystalline Ge and gives good results for several thermodynamic properties of the crystalline phase and the phonon dispersion relations of the crystal.
