R. Gaisch et al., INTERNAL STRUCTURE OF C-60 FULLERENE MOLECULES AS REVEALED BY LOW-TEMPERATURE STM, Applied physics. A, Solids and surfaces, 57(2), 1993, pp. 207-210
We have performed Scanning Tunneling Microscopy (STM) in ultra-high va
cuum at low temperatures (5 and 50K) of unordered and ordered C60 laye
rs adsorbed on a Au(110) surface. STM topographs of the frozen C60 mol
ecules reveal four symmetric patterns within single molecules, which m
ay be associated with different orientations of the fullerenes on a hi
ghly corrugated gold substrate.
