We report on the temperature-dependent transport behaviors of large-area molecular junctions fabricated with poly-(3,4-ethylene-dioxythiophene) stabilized with polystyrene sulphonic acid (PEDOT:PSS) interlayer electrodes and the archetypal benzenethiol molecules. In this study, we investigated two different benzenethiol molecules: 4-methylbenzenethiol (MBT) and 1,4-benzenedithiol (BDT), which have the identical backbone structure but different top end-groups. The charge transport through the molecular junctions was dominated by distinct interfacial contact properties between the PEDOT:PSS electrodes and the component molecules. We also observed that the electrical characteristics of the MBT junctions are influenced by the PEDOT grain size, particularly depending on the annealing temperature.

The electronic properties in the quasi-one-dimensional Fabre salts are strongly affected by electronic correlations along the molecular stacks, but also by the interactions with the anions located in a cage that is formed by the methyl end groups. We systematically compare the charge transport in deuterated and protonated (TMTTF)2X salts with the anions X = Br, PF6, SbF6, and ClO4, ranging from Mott and Efros–Shklovskii variable-range hopping to activated band transport with a temperature dependent energy gap. The strong dependence of charge localization and ordering on the anion size and deuteration confirms the subtle structural involvement of the anions in the charge transport along the TMTTF stack.

In large area molecular junctions, defects are always present and can be caused by impurities and/or defects in the electrode materials and/or SAMs, but how they affect the electrical characteristics of junctions has rarely been studied.
