论文摘要
了解域结构的动态行为对于超弹性独立的铁电薄膜的设计和应用至关重要。当前，相位模拟是一种强大的工具，用于观察，探索和揭示介质量表中铁电材料中的域切换行为和相变。本综述总结了在理论解释，机械响应和域结构的演化中，自电薄膜，皱纹结构和纳米弹簧的最新进展。此外，确认并讨论了超弹性铁电纳米结构中应变与铁电极极化之间的牢固耦合关系，这为自电薄膜系统的自由融合的新设计策略提供了新的设计策略。为了进一步促进独立的铁电薄膜系统的创新开发和应用，评论以摘要和对独立铁电薄膜的理论模型的概述结束。
Understanding the dynamic behavior of the domain structure is critical to the design and application of super-elastic freestanding ferroelectric thin films. The phase-field simulation is currently a powerful tool for observing, exploring, and revealing domain switching behavior and phase transition in ferroelectric materials at the mesoscopic scale. The present review summarizes the recent progress of phase-field methods in the theoretical interpretation, mechanical response, and domain structure evolution of freestanding ferroelectric thin films, wrinkled structures, and nano-springs. Furthermore, the strong coupling relationship between strain and ferroelectric polarization in super-elastic ferroelectric nanostructures is confirmed and discussed, which brings new design strategies for strain engineering of freestanding ferroelectric thin film systems. To further promote the innovative development and application of the freestanding ferroelectric thin film system, the review ends with a summary and an outlook on the theoretical model of the freestanding ferroelectric thin film.
