We investigate the electronic structures, optical properties and perform a population analysis of the highpressure phase of boron (Ξ³ -B 28 ) by the norm-conserving pseudopotential density functional method. We employ the Perdew-Burke-Eruzerhof (PBE) form of the generalized gradient approximation (GG

The structural, electronic, and optical properties of LiF are investigated at high pressures using the plane-wave pseudo-potential density functional method (DFT) within the generalized gradient approximation (GGA). From the analysis of Gibbs free energies, we find that no phase transition takes pla
