Figure 4

Calculated electronic structures of Pb islands on the hexagonal domain. (A) Atomic scale model structure for H-Pb phase. Black, blue and red circles in diamond unitcell correspond to the region of the A, B and C. Heights distribution of 2 ML Pb film is shown. The distance of upper and lower Te layers is about 0.28 nm. The 1 nm vertical scale bar is shown for eyes. The maximum vertical corrugation in this calculation is about 0.07 nm, which is about half of the experimental value. (B) The stacking mode of each site within a Moiré unitcell. (C–E) Calculated dI/dV maps of the 1st quantum well state at 2.14, 2.28 and 2.38 eV. Color scale spans 17%, 78% and 100% of LDOS maxima in (C), (D) and (E), respectively.
