Abstract
Scanning force microscopy (SFM) was employed to characterize C60 islan d films in an ultra-high vacuum (UHV). The initial growth stage of C60 on NaCl cleavage faces and nanotribological properties of this solid lubricant are investigated. In comparison to the NaCl(001) face, highe r friction is measured on the C60 islands, resulting in a ratio of fri ction of 1:3 for NaCl:C60. The friction coefficient of the (111) orien ted C60 island is determined to be 0.15+/-0.05. High-resolution SFM im ages reveal the hexagonal lattice of the unreconstructed (111) top sur faces and the overgrowth relationships of the C60 islands.
