Figure 1: A molecular junction (top) consists of a single molecule (in this case, benzene) that spans metal electrodes. By measuring the conductance through thousands of similarly prepared molecular junctions, it is possible to build a conductance histogram (bottom). The two histograms shown here correspond to a platinum atomic point contact that is formed with (blue) and without (red) a benzene molecule traversing it. As the blue curve shows, the Leiden group is able to achieve a conductance of $1G0$ across the molecular junction.
