|Outline of Final Research Achievements
We have constructed an ultrahigh-resolution three-dimensional spin- and angle-resolved photoemission spectrometer to elucidate the electronic states of novel functional materials such as spintronics-related materials. By developing a three-dimensional spin detector based on the very-low-energy-electron-diffraction method, we have obtained spin-resolved photoemission intensity two-orders-of-magnitude higher than that of the previous spin-resolved system. We have also achieved the energy resolution of 5 meV in the spin-resolved ARPES measurement, which is the world best at present. By using this spin-resolved system as well as synchrotron radiation, we have performed ARPES measurements on novel functional materials such as topological insulators, Rashba metals, and iron-based superconductors. We have succeeded in directly determining the fine electronic states in the vicinity of Fermi level responsible for the anomalous physical properties and novel quantum phenomena.
