    • 17 In this model, the enhanced visibility of the moiré pattern is explained in terms of the larger decay length of the long-periodicity wave function, which is associated with the moiré lattice and which is produced by multiple scattering. The exact imaging mechanism is not important in the present context though, since the presence of a moiré pattern unambiguously proves the presence of a (nearly) hexagonal CO adsorbate layer.

    • A sin(π - α) (2) π - α = π/3 - Ψ (3) ψΨ is taken to be the smallest positive angle between the substrate and moiré lattices. This set of equations allows a determination of all relevant angles and lattice vectors.

    • 3 exhibit clear spots at temperatures below and more diffuse spots at room temperature, which points to some degree of overlayer disorder at room temperature. The clear LEED pattern can be recovered by sample cooling, and hence the coverage is the same in both cases (θ = 0.5).
