- Self-introduction
- I am studying surface electronic states of materials experimentally using photoelectron spectroscopy (especially, spin-resolved photoelectron spectroscopy) at the synchrotron radiation beamline.
In addition, I am interested in to developing new experimental techniques and instruments for the surface science research.
