Research Summary
The structure and function of matter are intimately connected, yet observing both simultaneously at the atomic scale has long been a major challenge. Using our originally developed photon scanning tunneling microscope, we have realized diverse spectroscopic measurements with atomic-scale resolution. This team aims to further advance atomic-scale spectroscopy to determine the structures of molecules that play key roles in biological systems and organic electronics, and to measure their corresponding energy conversion functions with atomic resolution. By elucidating the correlation between structure and function with unprecedented precision, we seek to create novel energy conversion functionalities through precise control of local structures.
