The metal-molecule junction plays a critical rule in molecular electronics applications. In the work presented here, various methods were used to make metal-molecule nano-junctions on self-assembled monolayers (SAM), including vacuum evaporation of metal, nano-transfer printing (nTP), shadow angle deposition on a quartz tip, e-beam lithography based nano-fabrication, as well as direct interaction in conductive atomic-force microscopy (CAFM). The junctions were characterized by both structural (SPM, SEM, TEM) and electronic methods for different thiol molecules. A comparison of results is discussed.
