Abstract

Understanding the dynamic behavior of domain structures is critical to the design and application of super-elastic freestanding ferroelectric thin films. Phase-field simulations represent a powerful tool for observing, exploring and revealing the domain-switching behavior and phase transitions in ferroelectric materials at the mesoscopic scale. This review summarizes the recent theoretical progress regarding phase-field methods in freestanding ferroelectric thin films and novel buckling-induced wrinkled and helical structures. Furthermore, the strong coupling relationship between strain and ferroelectric polarization in super-elastic ferroelectric nanostructures is confirmed and discussed, resulting in new design strategies for the strain engineering of freestanding ferroelectric thin film systems. Finally, to further promote the innovative development and application of freestanding ferroelectric thin film systems, this review provides a summary and outlook on the theoretical modeling of freestanding ferroelectric thin films.

基于相场模拟的超弹性独立铁电薄膜设计

了解畴结构的动力学行为对超弹性独立铁电薄膜的设计和应用至关重要。相场模拟是在介观尺度上观察、探索和揭示铁电材料的畴切换行为和相变的有力工具。本文综述了近年来在独立铁电薄膜和新型屈曲诱导的起皱和螺旋结构中的相场方法的理论进展。此外，还证实并讨论了超弹性铁电纳米结构中应变与铁电极化之间的强耦合关系，为独立铁电薄膜系统的应变工程设计提供了新的策略。最后，为了进一步促进独立铁电薄膜系统的创新发展和应用，本文对独立铁电薄膜的理论建模进行了总结和展望。

期刊介绍： Micro and Nanostructures is a journal disseminating the science and technology of micro-structures and nano-structures in materials and their devices, including individual and collective use of semiconductors, metals and insulators for the exploitation of their unique properties. The journal hosts papers dealing with fundamental and applied experimental research as well as theoretical studies. Fields of interest, including emerging ones, cover: • Novel micro and nanostructures • Nanomaterials (nanowires, nanodots, 2D materials ) and devices • Synthetic heterostructures • Plasmonics • Micro and nano-defects in materials (semiconductor, metal and insulators) • Surfaces and interfaces of thin films In addition to Research Papers, the journal aims at publishing Topical Reviews providing insights into rapidly evolving or more mature fields. Written by leading researchers in their respective fields, those articles are commissioned by the Editorial Board.
