First Principles Study of Size Effect in BaTiO3 Ultrathin Films
Published online by Cambridge University Press: 01 February 2011
Abstract
Properties and phase transition behaviors of ferroelectric thin films that are different from that of their bulk form is usually referred to as size effect. A first-principles-based scheme is used to investigate the effects of four important factors contributing to the size effects in epitaxial (001) BaTiO3 ultrathin films: misfit strain, existence of surface, film thickness, and electrical boundary conditions.
