Abstract

The structure and stability of a quasiperiodic Na monolayer formed on a five-fold surface of an icosahedral Al-Pd-Mn quasicrystal have been investigated using ab initio density-functional methods. The structural model of the adsorbed monolayer has been constructed on the basis of a mapping of the potential-energy landscape of an isolated adatom on the five-fold surface of i-Al-Pd-Mn. Na atoms adsorbed on the surface arranged to a highly regular quasiperiodic monolayer. The quasiperiodic ordering can be described by a tiling of decagons, hexagons, boats and pentagonal stars (DHBS). The coverage density of the adsorbed monolayer is 0.067 atoms/2
