M. Causa, and A. Zupan, Density Functional LCAO calculation of periodic systems. A posteriori correction of the Hartree Fock Energy of covalent and ionic crystals, Chem. Phys. Lett. 220, 145-153 (1994).


Abstract:

Numerous density functional theory formulas proposed in the literature are used to compute the total electronic energy of solids, integrating a posteriori functionals of electronic density, obtained with the periodic linear combination of the atomic orbitals Hartree-Fock method. Formation energies, equilibrium geometries and bulk moduli are calculated for a set of 18 covalent, ionic and semi-ionic crystals. A set of 11 density functionals models is used. The calculated observables are compared with experimental data; a statistical analysis is performed to compare the models with greater ease.
