Outline of Final Research Achievements

The present research on transport phenomena at surfaces of strong spin-orbit coupling materials has provided the following results. (1) Direct detection of suppression of back scattering of surface-state carriers on topological insulators. (2) Detection of photogalvanic effect (spin-polarized current induced by irradiation of circularly polarized light) at Rashba-type spin-split surface states. (3) Detection of energy-gap opening in a topological Dirac-cone type state by proximity effect of magnetic material. (4) Detection of spin Hall effect at ultrathin films of topological insulators. (5) Discovery of superconductivity at Rashba-type spin-split surface states. (6) Discovery of superconductivity at Ca-intercalated double-layer graphene.
