Nonlocal model pseudo-potential. II - Diamond and BNsph
Abstract
An a priori model nonlocal pseudo-potential based on a spherical Fermi surface approximation is used here to calculate the physical characteristics of covalent and ion-covalent cubic crystals. The coupling energy, lattice spacing, bulk modulus of elasticity, and forbidden zone width calculated for diamond and BNsph by the pseudo-potential method are found to be in god agreement with experimental data.
