The C 60 film was obtained by depositing 2-3 ML of C 60 molecules on a highly oriented pyrolytic graphite surface. The as-deposited Lu-C 82 molecules were observed to form various structures on the C 60 film. The nucleation behavior of Lu-C 82 was compared with that of Nd-C 82 and Tb-C 82 on the C 60 film. These structures were explained based on the interactions of Lu-C 82 -C 60 , Lu-C 82 -Lu-C 82 , and Lu-C 82 scanning tunneling microscopy tip.

“…Organized fullerene nanostructures, as a unique platform for supramolecular chemistry 15,16 and as a resistive mask for photolithography when polymerized 17 are of great interest.

“…3,12 The adsorption characteristics are different from those of Lu@C 82 on a C 60 film, in which an accumulation of Lu@C 82 molecules is observed near the step edge. 5 The Dy@C 82 molecules neither migrate toward the step edge nor make significant clusters even after the substrate was heated up to 200°C; the STM image was measured at 295 K after annealing. These results imply that Dy@C 82 molecules are strongly bound by the Si surface.…”

“…Recently, the adsorption characteristics of metallofullerenes on semiconductor surfaces have been studied extensively by STM. [2][3][4][5][6] A STM image of Sc 2 @C 84 adsorbed on Si(100)-(2ϫ1) surface was first reported by Shinohara et al and showed a nearly spherical structure of the Sc 2 @C 84 molecule. 2 The first layer of Sc 2 @C 84 was not ordered, owing to strong interactions between the surface and the molecules.…”

“…Shi et al investigated Tb@C 82 molecules adsorbed on Si(100) 2 × 1 surface and the C 60 film with an ultrahigh vacuum scanning tunneling microscope (UHV-STM) [18]. It was found that the Tb@C 82 molecules were randomly distributed on the surface of Si(100) but form a close-packing monolayer on the C 60 film.…”

“…Fullerenes with metal atoms encapsulated (endohedral metallofullerenes) are novel forms of fullerene-based materials [18][19][20]. Shi et al investigated Tb@C 82 molecules adsorbed on Si(100) 2 × 1 surface and the C 60 film with an ultrahigh vacuum scanning tunneling microscope (UHV-STM) [18].…”
