In this project about STUDY OF THE STRUCTURE ELECTRONIC OF THE PbTiO3 MATERIAL is presented results, discussions and conclusions to respect of the use of theoretical-computational chemistry in the modeling of structures type Perovskites at applications in the eletro-electronic area. It was used ab initio methodology and the Density of Funcional Theory (DFT) to calculate the structure electronic of the PbTiO3 (PT) e Pb1-xMxTiO3 (M = Ca, Sr e Ba) materials. It was idealized this propose due to need of better understanding the influence of the surface, the substitution of atoms and defects in the lattice ceramic type Perovskites and anticipate tendencies through modeling of these materials. The density of states (DOS), bands structure, Mullike...
