Abstract

We report our recent study of the electronic and geometric structure of Sc-encapsulated fullerenes (metallofullerenes) ScC₇₄, Sc₂C₇₄, and Sc₂C₈₄ adsorption on the Si(100)2×1 surface with field ion scanning tunneling microscopy. A comparison with the pristine C₆₀ and C₈₄ confirmed the assumption that the Sc atoms are encapsulated inside the carbon cage. The charge transfer from the Sc atoms to the carbon cage is evidenced. The presented results also show that these metallofullerenes do not prefer to form dimers or trimers.
