Electrical Characteristics of Benzenedithiol versus Methylbenzenthiol Self-Assembled Monolayers in Multilayer Graphene-Electrode Molecular Junctions

초록

We report our recent results of fabrication and characterization of molecular electronic devices using benzene-based self-assembled monolayers (SAMs) and multilayer graphene (MLG) electrodes as the top electrode. In particular, we compared the electrical characteristics of two different benzenethiol molecules; 4-methylbenzenethiol (MBT) and benzene-1,4-dithiol (BDT), which have the same backbone structure but different end-group. From the analysis, we found that the electrical characteristics of the devices showed no significant difference. We investigated that the background of this result is a physisorbed contact properties between graphene electrode and molecular layer.
