| SAMS emerged, with the active encouragement of Art Adamson, as the most convenient and versatile point of entry into organic surface science. Superficially, SAMs seem to be relatively simple systems: in essence, 2D organic crystals supported epitaxially on a metal film. The underlying molecular reality is more complicated, and SAMs are known to have many types of local irregularities and heterogeneities. In some types of experiments, those irregularities may be relatively unimportant; in others, very important. This talk will describe studies of electron transport across SAMs using junctions of the form metal/SAM//SAM/mercury, and the use of SAMs to study the mechanisms of this process. For most SAMs, tunneling is probably the most important contribution to electron transport in these systems, but confirming reproducibility and mechanism in these systems is a challenging experimental problem. |
