We present results of numerical computation on some characteristics of BaTiO3 such as total
energy, rgy, 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.
