Scanning tunnelling microscopic investigation of fullerene monolayers.

C(60) fullerene monolayers have been investigated by scanning tunnelling microscopy/spectroscopy. Single C(60) molecules have been resolved and a regular surface lattice structure of fullerene - in - surfactant is observed. Tunnel electron spectroscopic measurements results in typical I(V) curves which are interpreted in terms of the two-junction Coulomb blockade effect.
