摘要
The electronic structure and electron density, in tetragonal crystal BaTiO3 are studied using full potential-linearized augmented plane wave method in the framework density functional theory with the generalized gradient approximation. The results show a direct band gap of 2.3eV at the F point in the Brillouin zone. The electron density distribution indicated that the bond between Ba and TiO3 is often ionic and bond between Ti and O is covalent.
