Abstract

RECENT developments in the synthesis of macroscopic amounts of the C₆₀ and C₇₀ carbon clusters^1–3 have made possible spectroscopic^1,2,4–7 studies of these species. Infrared^1,2 and vibrational Raman⁴ spectra strongly support the proposed 'soccer ball' structure for the C₆₀ cluster⁸, and NMR spectroscopy directly confirms its icosahedral symmetry^5,6. Here we present images of C₆₀ clusters obtained with the scanning tunnelling microscope. These species are roughly spherical and form mobile hexagonal arrays on a Au(lll) surface with an intercluster spacing of 11.0 Å Brighter features evident in the arrays are tentatively identified as C₇₀ clusters.
