Figure 4: Growth and stability, and long-range order of the Pb overlayer.
From: Templated three-dimensional growth of quasicrystalline lead
(a) Variation of XPS intensity of the substrate (In 3d) and film (Pb 4f) as a function of deposition time, fitted with lines of different gradients. Error in intensity is shown by green bars. Inset: the ratio of Pb 4f and In 3d intensity after annealing the Pb-covered surface at different temperatures. The intensity corresponding to the first, second and underlayers is marked by arrows. (b) LEED pattern after formation of the second layer Pb taken using MCP-LEED optics (beam energy 24 eV).
