Two-Dimensional Metallicity with a Large Spin-Orbit Splitting: DFT Calculations of the Atomic, Electronic, and Spin Structures of the Au/Ge(111)- Surface

Figure 4

Planar average of the modulus square of the wave functions chosen in Figure 3(b). The red curve with the label “Au” corresponds to the surface state of the Au- and electron-like character. The blue curve with the label “Ge” corresponds to the Ge- and hole-like character. The -zero is at the position of the Au-plane. The red and black balks in the bottom of the figure show the positions of the Au and Ge atomic layers.
