Abstract

Dy@C₈₂ and Dy@C₆₀ adsorbed on Si(111)−(7×7) surface are investigated by scanning tunneling microscopy (STM) at 295 K. The Dy@C₈₂ molecules in the first layer are adsorbed on the Si(111)−(7×7) surface without formation of islands and nucleation, and the internal structure of the Dy@C₈₂ molecule is first observed on the surface at 295 K. The average heights of the Dy@C₈₂ molecules in the first and second layers are estimated to be 7.2 and 10.8Å, respectively, by STM. These results suggest strong interactions between the Si atoms and the Dy@C₈₂ molecules in the first layer. The STM image reveals that the Dy@C₆₀ molecule is nearly spherical, showing that the metal endohedral C₆₀ possesses a cage-form structure.
