PbTiO3-based perovskite ferroelectric and multiferroic thin films

Abstract

Ferroelectric thin films, especially PbTiO3-based perovskite thin films which possess robust spontaneous electrical polarization, are widely investigated and applied in various devices. With the advances in synthesis, characterization and calculation techniques, diverse phenomena and properties are uncovered in the ferroelectric thin films. Herein some typical PbTiO3-based perovskite thin films through composition control are introduced, which gives more choices with various ferroelectric or other properties. Strain engineering, as well as some other interfacial effects, is also included to show the possibilities to control the lattice structure, the electronic structure as well as domain structure which are closely connected to the ferroelectricity. Multiferroic thin films, which could achieve the magnetic-field-controlled polarization reverse, expand the novel applications of ferroelectric thin films. Typical and remarkable progress in the multiferroic PbTiO3-based perovskite thin films are involved here. Critical problems such as leakage current and fatigue hinder the practical use of the ferroelectric and multiferroic thin films, which are also included in this article.
