Abnormal intermolecular interaction between overlayer C₆₀ molecules due to induced dipole moments in C₆₀ thin films adsorbed on substrates

The physical properties that occurs in fullerene molecules adsorbed on substrates were analyzed. The possible net electron charge transfer occurring from the substrate to the first-layer fullerene molecules are discussed in detail. A dipole layer at the interface and in turn a dipole field above the substrate were observed.
