✦ Synopsis

SC,& ( n = 1,2) and SC&~ metallofullerenes (MF) , adsorbed on the Si ( 100) 2 x 1 surface were studied by scanning tunneling microscopy. The MF molecule images were spherical and randomly distributed, similar to those of C6ar C,o, and Cs4, but were slightly larger than those of the pristine fullerenes. These results suggest that the SC atoms were trapped inside the fullerene cages, with a significant charge transfer from the metal atom.
