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 3 d on titanium and 2 p orbital on oxygen states, we also include weak hybridization between the Ba 6 s and O 2 p tates. The results are compared with those of other more sophisticated methods.
