Title
Density functional theory (DFT) investigation on the structure and electronic properties of the cubic perovskite PbTiO3
Abstract

This paper describes how to build models of PbTiO3 crystal in the material studio and how to do CASTEP calculation. This article focuses on discussing the best CASTEP calculation and pseudopotential, and analyzing the structure and properties of PbTiO3, namely the band structure and density of states (DOS). The calculated results are in good agreement with the experimental ones. The purpose of this paper is to prove the feasibility and accuracy of calculation.
