Investigating single molecular orbitals in fullerenes by novel STM

Investigating single molecular orbitals in fullerenes by a novel scanning tunnelling microscopy mode of operation.

Energy-resolved differential-conductance maps have been measured for individual C60 molecules adsorbed on a Cu(111) surface by means of low-temperature scanning tunnelling microscopy. To allow for the quantitative interpretation of these images as maps of local density of states a novel scanning mode has been applied, with the feedback loop switched off and the tip scanning in circles instead of scan lines.

The energy-resolved maps obtained by this method can then be compared to density functional theory calculations. Thereby the nature of the fullerene-surface interaction is examined.
