| Research Abstract |
The atomic and electronic structures of nanowire(one-dimensional ; 1D) and two-dimensional(2D) structures which are formed by one atomic-layer of gold deposition on germanium(001) and(111) substrates have been investigated. The nanowire structure has been revealed to have a metallic surface state with smaller effective mass in the perpendicular direction to the wire, which is contrary to intuitive expectation of 1D electronic structure. The 2D structure has been revealed to have a metallic surface state with Rashba-type spin split due to a large spin-orbit interaction.
