    • A number of workers have demonstrated rectification by organic monolayers using scanning probe microscopy. We focus here on results obtained from measurements on ensembles of molecules. For example, see: Pomerantz, M.; A. Aviram, McCorkle, R. A.; Li, L.; Schrott, A. G. Science 1992, 255, 1115-1118; Dhirani, A.; Lin, P.-H.; Guyot-Sionnest, P.; Zehner R. W.; Sita, L. R. J. Chem. Phys. 1997, 106, 5249-5253.

    • The refractive index of the SAM was assumed to be the same as that for a SAM of an alkanethiolate (1.45). We do not believe that the assumption of this value of the refractive index will create a substantial error in the derived value of the thickness.

    • We base our discussion on a valence orbital representation and treat the orbitals of TCNQ separately from those of the alkyl chain. The π symmetry states of TCNQ are unlikely to mix strongly with the alkyl chain due to symmetry and difference in energy.

    • It is difficult to determine whether this assumption is valid for the junctions studied here. We assume that the qualitative predictions of the model are valid, but a more detailed analysis of the system will require testing of this assumption.
