Systematic cross-linking changes within a self-assembled monolayer in a nanogap junction: a tool for investigating the intermolecular electronic coupling.

Here, we show that a controllable cross-linking within a self-assembled monolayer can be used as a tool for investigating the (lateral) intermolecular coupling between adjacent organic molecules. We draw this conclusion based on macroscopic electrical experiments with self-assembled hexyltrichlorosilane (HTS) having different degrees of Si-O-Si intermolecular bonds in a planar nanogap junction.
