Probing Lateral Charge Transport in Single Molecule Layers: How Charge is Transported Over Long Distances in Fullerene Self-Assembled Monolayers

Abstract

The lateral conductance of a single monolayer of fullerene on an insulating substrate is investigated using conduction atomic force microscopy. The quadratic dependence of the of I(V) observed contrasts the exponential fall-off of the current as a function of distance. A similar behavior is observed for an anthracene monolayer, which is found to be ca. 104 times less conducting than the fullerene monolayer under similar conditions.
