Abstract
Charge transport through alkanes and para‐phenylene oligomers is investigated in large‐area molecular junctions. The molecules are self‐assembled in a monolayer and contacted with a top electrode consisting of poly(3,4‐ethylenedioxythiophene)–poly(4‐styrenesulfonic acid) (PEDOT:PSS). The complete set of J(V,T) characteristics of both saturated and π‐conjugated molecules can be described quantitatively by a single equation with only two fit parameters. The derived parameters, in combination with a variation of the bulk conductivity of PEDOT:PSS, demonstrate that the absolute junction resistance is factorized with that of PEDOT:PSS.Keywords
