Abstract C60 single crystals oriented at [111] about 1 μm in size, were grown in C60 film on NaCl (001) substrate. Bilayer films of nickel, gold, silver, and indium over C60 on NaCl substrate prepared by vacuum deposition method were studied with a transmission electron microscope. It was found that for different kinds of metals, their nucleation and growth characteristics on C60 (111) surface are quite different. This phenomenon is mainly attributed to different activation energies of the four metals. Analyses of the experimental results indicate that the activation energies of Ni, Au, Ag, and In adatoms on C60(111) surface change in a descent order.
