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

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