Charge Transport Characteristics of the PEDOT:PSS Interlayer Electrode/Molecule Physisorbed Contact in Large-Area
Abstract:
Here we studied the effect of electrical contact between the PEDOT:PSS conducting polymer and the prototype benzenethiol molecules on the charge transport through the PEDOT:PSS-electrode molecular junctions. For this study, two different benzenethiol molecules were incorporated into the molecular junctions: 4-methylbenzenethiol (MBT) and 1,4-benzenedithiol (BDT). They have the same backbone structure but different top end-group. By investigating the MBT and BDT junctions with the PEDOT:PSS electrode, we demonstrated that the charge transport characteristics were dominated by distinct electrical contact properties at the PEDOT:PSS/molecule interface.
