The structural and electronic properties of the rhombohedral phase of the A-site-substituted perovskite Sodium bismuth titanate Bi 1 /2Na 1/2 TiO 3 (BNT) were investigated via the density functional theory (DFT) that implemented in the CASTEP module in the Materials Studio software. I also investigated the impacts of atoms vacancy and oxygen-dopants on dielectric, electrical conductivity, and ferroelectric properties. The author expected that the defected on lead-free ferroelectric materials could extend the functional materials for innovative electronic applications.
