Photoemission Spectroscopy Group

The electrical and magnetic properties of materials are determined by the electrons moving within them. Therefore, it is extremely important to elucidate the behavior of electrons, which is the key to the expression of material functions, for the development of new materials and device design. We have been measuring the electronic states of materials in steady-state and operating environments using spin-angle-resolved photoemission spectroscopy and microscopic photoemission spectroscopy under electric field application, which can precisely measure the electronic states including spin. Recently, the evaluation of electronic states of quantum materials and magnetic materials has become an important research topic.
