| Research Abstract |
So far, spin-resolved photoemission measurement was very time consuming method because of the very low efficiency of the spin detector. Thus, the spin-resolved photoemission measurement with high energy- and angular-resolutions was impossible. In this project we have developed a new high-efficient spin-detector and combined with high-resolution photoelectron analyzer. More than 100 times higher efficiency has been achieved and the spin-resolved photoemission measurement with quite high energy- and angular resolutions has been realized.
