Fig. 7.3 Schematic representation of the two different setups for the benzene I-SET considered in
this paper. The molecule, lying on a dielectric substrate, is weakly contacted to source and drain
leads as well as capacitively gated. From [ 20 ]
Fig. 7.4 Stability diagram for the benzene I-SET contacted in the para (above) and meta (below)
configuration. Dot-dashed lines highlight the conductance cuts presented in Fig. 7.5 ,the dashed
lines the regions corresponding to the current traces presented in Figs. 7.6 and 7.8 ,the dotted
line the region corresponding to the current trace presented in Fig. 7.7 . The parameters used are

meta and para configurations (see Fig. 7.4 ). Striking are the selective reduction of
conductance and the appearance of regions of interference-driven current blocking
with associated negative differential conductance (NDC) when changing from the
para to the meta configuration.
