Rectified electron transfer across fullerene multilayers on ITO surface

Abstract

Stacks of fullerene layers were constructed on the ITO surface. The cyclic voltammetry and chronopotentiometry showed that the diffusion of Fe(CN)(6)(-3) to the ITO surface is inhibited in the presence of the fullerene layers, and that electrons are transferred across the fullerene films. Unidirectional electron transfer was observed, indicating a rectifying character of the fullerene-modified ITO electrodes.
