    Abstract

    We present an analysis of Sn film growth on the fivefold surface of the icosahedral Al-Cu-Fe quasicrystal at multilayer coverage. Scanning tunnelling microscopy of the Sn-deposited surface revealed that film morphology differed from terrace to terrace. Most terraces exhibited flat-topped clusters with preferential growth at the step edges, while a minority of terraces showed a smooth film. The height, lateral size and density of clusters also varied between terraces. Clusters have a preference for specific heights.
