Design of the Metal–Molecule Interaction at the Benzene Single-Molecule Junction

In this chapter, the influence of the strength of the metal–molecule interaction on the formation of a single-molecule junction with a high, well-defined conductance value was investigated. Although the Pt/benzene/Pt single-molecule junction exhibits high conductivity, its conductance value is not well defined. In order to restrict the configuration of the benzene molecule, the strength of the interaction between the metal and benzene should be reduced. Ag and Au are expected to interact more gently with the benzene than Pt. The moderately strong interaction between Ag and benzene successfully formed a single-molecule junction; however, Au did not form a single-molecule junction because of the formation of the linear atomic chain.
