single molecule
Single-molecule junctions, in which a single molecule bridges a nanogap between metallic electrodes, have attracted considerable attention for applications in molecular electronics. We have previously reported that σ-delocalized molecules based on the lone pairs of selenium atoms exhibit high electrical conductance and thermopower in single-molecule junctions. In this study, we investigate the electron transport properties of sulfur-based σ-delocalized molecules obtained by replacing selenium atoms with sulfur atoms and discuss the correlation between heteroatom-induced changes in the electronic structure and charge transport characteristics.
