We study the formation of structure when a layer of adatoms is deposited onto a substrate with quasicrystalline order. Molecular-dynamics calculations with simulated annealing show that the adsorbate layer forms ordered domains whose orientation is determined by the underlying substrate symmetry. The domain size is found to depend on the relative strength of the adatom interactions
with each other and the substrate, as well as the cooling rate of the growing film. These results are consistent with low-energy electron diffraction studies of Al grown on the decagonal surface of an Al-Co-Ni quasicrystal. We will also present and discuss the distribution of domain sizes, which shows scaling behavior.
