摘要

本文采用离散朗道型三维极化热力学势，研究了薄膜附着在衬底上的弹性约束下的开关动力学。我们已经证明180/sup 0/域反转和极化矢量旋转是可能的开关机制，取决于场强和弹性应力。研究了平面内偏振分量对开关的作用，并证明了实验结果的支持。

A model for switching in ferroelectric thin films by nucleation-growth of domains with three-dimensional polarization

In this paper we studied the switching kinetics using a discrete Landau-type three-dimensional polarization thermodynamic potential, with the elastic constraints of a film attached to a substrate. We have shown that 180/sup 0/ domain reversal and polarization vector rotations are possible switching mechanisms, depending on field strength and elastic stresses. The role of in-plane polarization components to switching has been investigated and shown to support experimental findings.
