Outline of Final Research Achievements

We have developed a novel method for fabricating single-molecule devices. In this method, a single conductive polymer chain is fabricated by a chain polymerization and connected to a single functional molecule. The purpose of this study is to develop and evaluate new methods of measuring electric transport properties of such single-molecule devices. We first examined appropriate insulating substrates for this study, and found that a hexagonal boron nitride was a good candidate. We then fabricated metal nano-electrodes on the substrate, and succeeded in creating single conductive polymer chains between the electrodes. In addition, we found selective adsorption of molecules on a molybdenum disulfide substrate, and also found the formation of arrays of gold nanoparticles on molecular layers.
