Reversible and irreversible polarization processes in ferroelectric ceramics and thin films
نویسندگان
چکیده
In this article, the separation between reversible and irreversible polarization where the reversible polarization component is determined by capacitance–voltage curve measurements, is used to characterize ferroelectric materials. After giving a thorough foundation of the method, it is used to investigate the influence of the composition on the reversible and irreversible polarization contributions in ferroelectric thin films and/or bulk ceramics. The reversible polarization is also monitored during fatigue. A comparison to bulk ceramics suggests that the domain wall motion in ferroelectric thin films is reduced compared to bulk ceramics. © 2003 American Institute of Physics. @DOI: 10.1063/1.1535748#

Tunable Schottky Barrier in Photovoltaic BiFeO3 Based Ferroelectric Composite Thin Films
We examine the photo-assisted polarization loop in a BiFeO3 thin film under UV light illumination. BiFeO3 thin film prepared by pulsed laser deposition method onto the BaTiO3 thin film and the polarization behavior has been measured under poling voltage. Our results show the engineered polarization due to controllable schottky barrier under inverse poling voltage. This control on schottky barri...

متن کاملAtomic mechanism of polarization-controlled surface reconstruction in ferroelectric thin films
At the ferroelectric surface, the broken translational symmetry induced bound charge should significantly alter the local atomic configurations. Experimentally revealing the atomic structure of ferroelectric surface, however, is very challenging due to the strong spatial variety between nano-sized domains, and strong interactions between the polarization and other structural parameters. Here, w...
متن کاملA Mesoscopic Electromechanical Theory of Ferroelectric Films and Ceramics
We present a multi-scale modelling framework to predict the effective electromechanical behavior of ferroelectric ceramics and thin films. This paper specifically focuses on the mesoscopic scale and models the effects of domains and domain switching taking into account intergranular constraints. Starting from the properties of the single crystal and the pre-poling granular texture, the theory p...
