Figure 2: Evolution of successive Pb layers.
From: Templated three-dimensional growth of quasicrystalline lead
STM images (180 Å × 145 Å) of a terrace of the fivefold i-Ag-In-Yb surface after deposition of Pb for 30 min (a) and 90 min (b). The inset is the height profile along a line indicated by an arrow, demonstrating the height of the first, second and intermediate layers. (c) Model structures corresponding to the white circles marked 1–3 in a and b, deduced from the calculations. Red spheres, Cd atoms; green, Yb; white, Pb in the first layer; blue, Pb in the second layer; grey, Pb in the intermediate layer.
