My research goal is to understand the fundamental mechanisms of interface properties in materials and devices, and to establish the guideline to design them from the atomic-scale. I mainly use atomic-resolution scanning transmission electron microscopy to directly characterize the atomic structures of materials interfaces. We are developing the researches as the following:
a) Grain boundary and interface studies in oxide materials
b) Development of scanning transmission electron microscopy (STEM) and related techniques
c) In-situ transmission electron microscopy studies of materials deformation and fractures
d) Nanocharacterization of heterogeneous catalysts e) Development of novel devices using crystalline defects
