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.
