Ferromaterials have ferroelectricity, ferroelasticity or ferromagnetism and are widely used in information storage, sensing, nonlinear optics and other fields. Miniaturization, flexibility and multi-functionality are important characteristics for the development of ferrous functional devices in the future. Two-dimensional layered van der Waals ferroelectric and piezoelectric materials have important application prospects in the fields of information functions and sensor devices in the post-Moore era due to their unique electronic structure and physical properties, rich physical property control methods, and easy construction of functional devices. . In this report, I will mainly report on the team’s development in this field in recent years, such as the design and preparation of new two-dimensional ferroelectric and piezoelectric crystals, the exploration of novel ferroelectricity and other physical properties, and the high-resolution micro-nano ferroelectricity Femtosecond laser micro-nano manufacturing of structures, etc.
