Outline of Final Research Achievements

We developed a method for cleaning the surfaces of topological Kondo insulator candidates SmB6 and YbB12, and performed local structure-dependent tunnel spectroscopy and quasiparticle interference measurement. In SmB6, the interference pattern depending on the electron energy indicating the existence of the surface state was clarified, and in YbB12, the surface structure dependence of the local density of states was clarified. In addition, a Co single atom was deposited on the surface of SmB6, and a change in the electronic state of the surface was found.
We completed a spin angle-resolved photoelectron spectroscopy (SARPES) measuring device using an 11eV laser, and measured the spin polarization band structure of a topological insulator with a resolution of 20 meV. We also developed a time-resolved SARPES and investigated the lifetime of its surface electronic state with a time resolution less than 2 psec.

Academic Significance and Societal Importance of the Research Achievements

量子力学の確立ともに強磁性の理解が大きく進みその社会実装も進んできた。さらに、最近は、電子のもつ磁性であるスピンが偏極した電子状態の理解も進み、強磁性だけでない多様なスピン偏極電子状態の社会的利用が提案されている。しかしながら、新しい物質においては、その物性の学術的理解はまだ不十分であり、確たる証拠基づいていない議論もある。本研究では、原子レベルで評価された良質表面試料作製法を開発し、スピン偏極電子状態に関する実験研究を行い、その定量的学術研究発展への道筋をつけたことに意義がある。今後の基礎研究の進展により学術的理解を深め、スピン偏極電子状態の社会応用への新しい発展が期待される。
