Bio Sketch
We aim to understand properties of emerging materials from the atomic-structure perspective, using tools including but not limited to TEM. More specifically, we are interested in:
• Exploring emerging physics such as ferroelectricity, ferroelasticity, and phase switching in novel 2D materials down to the monolayer thickness
• Understanding reaction mechanism on nanocatalyst surfaces, through capturing reaction dynamics using various in situ and ex situ characterization techniques including liquid and gas TEM holders
• Developing ultralow-dose TEM techniques to unravel the structure information in beam sensitive materials including hybrid perovskites, polymers, MOFs, and battery materials
• Developing novel 4D-STEM techniques to reveal the intrinsic electric and magnetic fields in functional materials at nanometer or even atomic scale
