    • Abstract


      We present results of numerical computation on some characteristics of BaTiO3 such as total energy, lattice constant, density of states, band structure etc using self-consistent tight binding method. Besides strong Ti–O bond between 3𝑑 on titanium and 2𝑝 orbital on oxygen states, we also include weak hybridization between the Ba 6𝑠 and O 2𝑝 states. The results are compared with those of other more sophisticated methods.
