The Density–Functional method, with Linear Combination of Atomic Orbitals, has been applied to eight crystals: the lattice equilibrium parameters, and the lattice formation energies have been calculated at the Hartree–Fock level ( HF ), at the hybrid Hartree–Fock Density‐Functional level ( DFT/HF ), and at the Kohn–Sham Density‐Functional level ( DFT ). The band structures and the electronic charge distributions calculated at the DFT and HF levels are compared. © 1994 John Wiley & Sons, Inc.
