Tunneling Across Single-Layer Graphene Electrode Monolayer Junctions
In this study, we present tunneling transport characteristics of chemically grafting aryl alkane monolayers onto single-layer graphene (SLG) electrodes. The molecular monolayers were sandwiched between two SLG electrodes, creating a vertical tunnel junction. Raman spectroscopic study
demonstrates that the aryl alkane molecules were successfully incorporated as an effective tunneling barrier between the SLG electrodes. The temperature-variable and length-dependent transport measurements, and transition voltage spectroscopy characterization consistently indicate that tunneling
is intrinsic transport properties of the SLG/monolayer/SLG junctions.
