| Outline of Final Research Achievements |
We studied the growth, structure adn electronic structure of Co atom adsorbed Bi/Ag(111)√3x√3 surface system. Co atoms nucleated atomically flat, triangular islands with an interface-induced Moire pattern. The d-band of the Co islands were found to shift to the Fermi level systematically with the increase in the Co island thickness.
We also studied a new surface alloy phase of Bi atoms and Si(111)√3x√3-Ag surface, and ultra-thin Bi(110) islands as candidates of the alternative sysytem with a large spin-split surface band by the Rashba effect and robust against Co atom adsorption.
