The adsorption of Xe and Ar on quasicrystalline Al–Ni–Co
The adsorption of Xe and Ar on quasicrystalline Al–Ni–Co
An interaction potential energy between and adsorbate (Xe and Ar) and the 10-fold Al-Ni-Co quasicrystal is computed by summing over all adsorbate-substrate interatomic interactions. The quasicrystal atoms' coordinates are obtained from LEED experiments and the Lennard-Jones parameters of Xe-Al, Xe-Ni and Xe-Co are found using semiempirical combining rules. The resulting …
