Perspective—Temperature Dependencies and Charge Transport Mechanisms in Molecular Tunneling Junctions Induced by Redox-Reactions

Abstract

In this perspective, we discuss complex charge transport behaviours induced by redox-reactions in molecular tunnelling junctions by gauging the development of charge transport theories which allow for more unified approaches between temperature-dependent and -independent transport. A context is drawn for current experimental works which previously demonstrated behaviours that could not have been explained by traditional Marcus and Landauer theories. The work discusses not only the reported temperature-independent long-range tunnelling and their corresponding theoretical explanations but also correlates the influence of structural and thermodynamic factors that influence such peculiar temperature dependencies in molecular junctions.
