About me

Research interests:

developing and applying the state-of-the-art TEM imaging and data analysis techniques in study of local atomic and electronic structures at surfaces, interfaces, and defects in materials, nanostructures, and devices.
The ultimate goal of my research is to quantitatively determine local atomic and electronic structures, to elucidate their dynamics and influences, thereby, to understand materials properties and phenomena mechanisms at atomic level.
