Abstract

2D ferroelectric materials present promising applications in information storage, sensor technology, and optoelectronics through their coupling with magnetics/valleytronics, mechanics, and optics, respectively. The integration of 2D ferroelectrics with magnetism enhances data storage density in memory devices by enabling electric-field-controlled magnetic states. Ferroelectric-valley coupling holds promise for high-speed, low-energy electronics by leveraging the electrical control of valley polarization. Ferroelectric-strain coupling results in various polar topologies, with potential applications in high-density data storage technologies and sensor devices. Moreover, the coupling between ferroelectrics and optics facilitates the development of nonlinear photonics based on ferroelectric materials. This review summarizes the latest theoretical progress in the coupling mechanisms, including the Dzyaloshinskii-Moriya-interaction-induced magnetoelectric coupling, symmetry-linked ferroelectric-valley coupling, ferroelectric-strain-coupling-generated polar topologies, and second-harmonic generation through ferroelectric-light interactions. The current challenges and future opportunities in harnessing the coupling in 2D ferroelectric materials for multifunctional applications are provided.

新出现的二维铁电多功能性：与磁学、谷电学、力学和光学相互作用的理论回顾

二维铁电材料通过与磁学/谷电学、力学和光学的耦合，分别在信息存储、传感器技术和光电子学领域呈现出广阔的应用前景。二维铁电材料与磁性的结合通过实现电场控制磁性状态，提高了存储设备的数据存储密度。铁电-山谷耦合利用山谷极化的电气控制，为高速、低能电子学带来了希望。铁电-应变耦合可产生各种极性拓扑结构，有望应用于高密度数据存储技术和传感器设备。此外，铁电和光学之间的耦合促进了基于铁电材料的非线性光子学的发展。这篇综述总结了耦合机制方面的最新理论进展，包括 Dzyaloshinskii-Moriya-interaction-induced magnetoelectric coupling、symmetry-link ferroelectric-valley coupling、ferroelectric-strain-coupling-generated polar topologies 以及通过 ferroelectric-light interactions 产生二次谐波。本文介绍了利用二维铁电材料中的耦合实现多功能应用的当前挑战和未来机遇。
