| We have realized a first-principles study of the structural, electronic, elastic and vibrational properties for the AB 2 O 4 cubic spinel structures, using the pseudopotential plane-waves approach based upon density functional theory and implemented in the MedeA-VASP package. We have computed the equilibrium structural parameters: the lattice constant and internal structural parameter. These results agree very well with experimental data. The electronic band structures, total and partial density of states of these materials are given. The electronic calculations reveal that AB 2 O 4 have a direct (Γ-Γ) band gap. We also calculated elastic constants, Bulk and Shear moduli, Young’s moduli and Poisson’s ratios for AB 2 O 4 AB 2 O 4 aggregates. The phonon dispersion curves of these compounds are calculated using the direct method. All results are in agreement with the available experimental data and other … |
