摘要：
Electronic band structures, densities of states, Compton profiles of MgxCa1-xO ternary alloy have been calculated by employing the linear combination of atomic orbitals (LCAO) method utilizing CRYSTAL code. The correlation and exchange potential is treated by the generalized-gradient approximation (GGA) given by Perdew-Burke-Ernzerhof (PBE) and Becke's ansatz respectively. Results obtained are in good agreement with earlier investigations. The study observes that band gap increases with the concentration of magnesium. Nature of bonding in the isovalent MgxCa1-xO compounds is also compared and it was found that MgO is more covalent.
