1. Develop a new second-order modulation (SOM) formulism. Based on atomic-scale observation and analysis of a new charge-lattice modulation wave in hole-doped LuFe2O4+δ, we develop a new second-order modulation (SOM) formulism with an unusual quasiperiodic singularity by introducing a well-defined secondary modulation vector in both the phase and amplitude parameter spaces, which is applicable to a wide range of ordered systems, advancing our understanding of the nature of singularity and modulation (Phys. Rev. Lett. 2019). 2. Develop a method for generating new ferroelectrics. Develop a method for driving paraelectrics into ferroelectric states via the introduction of M/O-deficient (M for metal) perovskite nanoregions to form coherent interface with the film matrix. Using this method, strong ferroelectricity, equivalent to that of classic ferroelectrics, is achieved in a prototype paraelectric strontium titanate film (Adv. Mater. 2021). 3. Atomic-scale investigations and control of rare earth multiferroics. Systematically explore the lattice, charge and spin interactions and regulation methods of hexagonal rare earth manganites/ferrites multiferroics and realize the control and performance improvement of the improper ferroelectricity and anti-ferromagnetism by using interface strain and defect engineering (ACS AMI 2017, 2016).
