Abstract

We have studied one-dimensional cluster formation of C₆₀, Y@C₈₂, and Gd@C₈₂ along the step of the Cu(111) 1×1 surface using a scanning tunneling microscope. It is found that the dimer is most abundant only for Y@C₈₂ which has one unpaired electron delocalized over the carbon cage, while the monomer is dominant in the cases of Gd@C₈₂ and C₆₀. It was concluded that the preferential dimer formation of Y@C₈₂ is mainly due to the interaction between the unpaired electrons. The interaction energy among fullerence molecules was estimated based on Walton's cluster theory.
