Main Academic Contributions
Focused on novel, multifunctional, ultra-fast, low-energy, intelligent information storage and processing. This involves the design of new structures and devices of ferroelectric, dielectric, ferromagnetic, and multiferroic materials. Key achievements include:
1. Using magnetoelectric coupling effects to design and build 4-8 resistance states multiferroic tunnel junction non-volatile information storage prototype devices, achieving a switching speed of up to 6 ns under a low voltage of 2 V. Also discovered new electronic synapse functionalities with magnetoelectric coupling memristive properties.
2. Uncovered new principles of magnetoelectric coupling interface reconstruction, discovering magnetoelectric coupling and resistive switching effects induced by atomic-scale interface ion reconstruction. Designed new magnetoelectric interface layers that increased the resistance switch ratio of multiferroic tunnel junctions by two orders of magnitude and achieved spin-polarized switch control and spin rectification effects.
3. Using band engineering and domain engineering to design ferroelectric tunnel junctions, achieved ultra-fast, low-energy, multi-resistance states, silicon-compatible non-volatile memory device prototypes. The neural network constructed based on ferroelectric tunnel junction simulation has a high online image recognition rate. Several results have been reported by domestic and international media such as AAAS EurekAlert, Science Daily, Phys.Org, TechXplore, Wiley-Materials Views China, People's Daily Online, China News Service, and China Science Daily. Responsible for several major projects, including the projects of National Science Foundation for Distinguished Young Scholars and key projects of the National Natural Science Foundation of China, and the Ministry of Science and Technology's key research and development plans.
