Probing the Atomic Structure and Dynamic Behaviors of Materials by In-situ Transmission Electron Microscopy

As advances in aberration-corrected transmission electron microscopy (TEM), the development of in situ techniques allows us to study the dynamic evolution of materials in response to applied fields and to changes in environments. In this talk, I will present our work on the development of in-situ TEM techniques for imaging electric polarization, probing the nucleation and growth of ferroelectric domains during electric polarization switching, and observing the dynamic reaction and structural evolution of catalysts under realistic conditions with atomic precision through a MEMS-based, electron-transparent closed cell with a heating stage.
