One-dimensionality of the spin-polarized surface conduction and valence bands of quasi-one-dimensional Bi chains on GaSb(110)-(2 $\times$ 1)

Yoshiyuki Ohtsubo, Naoki Tokumasu, Hiroshi Watanabe +8

Surface electronic structure and its one-dimensionality above and below the Fermi level ( $E_{F}$ ) were surveyed on the Bi/GaSb(110)-(2 $\times$ 1) surface hosting quasi-one-dimen…

Fermi level tuning of one-dimensional giant Rashba system on a semiconductor substrate: Bi/GaSb(110)-(2x1)

Takuto Nakamura, Yoshiyuki Ohtsubo, Naoki Tokumasu +10

We fabricated spin-polarized surface electronic states with tunable Fermi level from semiconductor to low-dimensional metal in the Bi/GaSb(110)-(2 $\times$ 1) surface using angle-res…
