Self-introduction
We are investigating electronic states on various superconductors and related materials. Using a scanning tunneling microscope that can observe the atomic arrangement on the surface of a superconductor, we observe the electronic density of state by tunneling spectroscopy in each atom. Furthermore, together with the break junction tunneling spectroscopy, we will clarify the superconducting mechanism and the lead to the higher-performance superconductors.
