Abstract

Using STM, we show several off-stoichiometric impurity phases detected at the 2-fold Al–Pd–Mn quasicrystal surface. By comparing the observed surface structure to planes from similar bulk phases in the Al–Pd system, we identify these phases as β–Al–Pd and Pd5Mn3. C60 is adsorbed at these domains, forming simple hexagonal close packed (hcp) structures. We identify potential adsorption schemes, and compare the adsorption behaviour to C60 on the quasicrystalline phase.
