Abstract

We present a scanning tunnelling microscopy (STM) characterization of C 60 layers grown on a Pt(111) substrate at room temperature. Fullerenes diffuse on the surface until finding steps in which they remain anchored forming one-dimensional molecular lines. These rows are seed for the growth of ordered islands, which expand on the Pt atomic terraces with two different orientations: either parallel to main crystallographic direction of the substrate, or rotated by 30°. For coverages near to the monolayer a second layer appears before completing the first one.
