[5p-A504-11] [Molecular Electronics and Bioelectronics Award Speech] Investigation and control of the interface structure of single-molecule junction utilizing surface enhanced Raman scattering
Keywords:single-molecule junction, surface enhanced Raman scattering
Single-molecule junctions have attracted wide attention due to their potential application in molecular electronics. Since their interface structures significantly affect the electron transport in single-molecule junctions, investigation of the interface is fundamental to understanding these systems. In this research, a novel system was developed for the measurement of current-voltage (I-V) response and surface enhanced Raman scattering (SERS). The measurement system revealed that 1,4-benzenedithiol formed adsorption sites on the gold electrodes, and SERS was drastically enhanced only at the bridge sites. This finding demonstrates the novel possibility of using SERS for the detection of adsorption sites in single-molecule junctions.
