Intermolecular interactions can affect the conduction properties of molecular junctions in several ways: Direct and through-substrate electronic interactions affect the spectral properties (density of states) of the conducting junction, intermolecular electrostatic interactions affect the positioning of molecular electronic energies and thereby the nature of interface polarization. Such interactions also influence the screening properties of the junction and consequently the electrostatic potential profile across the biased junction. Other consequences include effects on junction mechanical properties that can be manifested by a different temperature dependence of conduction for a single molecule and for a molecular layer, as well as effects on optical response that may be important, for example, for the junction response associated with light induced switching. This article discusses some of these effects and their implications for the performance of molecular junctions.
