Abstract

Field ion scanning tunneling microscopy was employed to investigate C60 film growth on a GaAs(001)-2×6 surface prepared by molecular-beam epitaxy. The corrugated potential of the 2×6 substrate forces the first monolayer structure to be strongly modified, resulting in formation of a "double-chain" commensurate structure. A stronger interaction between C60 and Ga versus C60 and As was observed. This interaction of C60 and the substrate, however, is limited for two to three monolayers at the interface and the competing intermolecular interaction governs the three-dimensional growth of multiple-layer C60 crystalline film of the (111) orientation with a high density of screw dislocations.
