Outline of Final Research Achievements

Toward realizing single molecular electronic devices, much attention has been paid to study the transport property of single molecule junction bridged between conductive electrodes. Since the conductance of single molecular junction strongly depends on the molecular conformation, precise manipulation of molecular conformation will enable us to control the transport characteristics
In this study, we have developed new method to realize three-dimensional control of molecular conformation with sub angstrom resolution, which analyze the influence of molecular conformation on the carrier transport in single molecular junction. By using the method, we have observed a single molecular conductance switch whose on/off state could be regulated by cis-trans conformational change.
