We are an experimental research group in condensed matter physics, materials science, and electron microscopy. Our group is dedicated to the study of atomic-scale interface science by using cutting-edge electron microscopy techniques. We investigate the electronic structure and lattice dynamics of interfaces, crystal defects, and low-dimensional materials, as well as their dispersion relationships by 4D-EELS with our advanced facilities.

(1) High energy resolution and momentum-resolved electron energy loss spectroscopy

(2) Lattice dynamics on interfaces

(3) Low-dimensional ferroelectrics and topological defects

(4) Van der Waals epitaxy
