| Research Abstract |
The electronic states of the molecular devices should be perturbed by not only the interactions with the metal electrode but also the induced charge and/or the applied bias in the operation. In this study, we attempted the direct observation of the electronic states of molecules under the operative conditions, for deep understanding of its electric properties. Using a fluorescence-yield x-ray absorption spectroscopy, the spectral change for molecular thin films depending on the applied bias was successively detected. Based on the analysis of the results, the functional self-assembled monolayers consisting of the electrically different group were fabricated, and their electronic states were experimentally characterized. Through this study, the design for a new type of single molecular devices was obtained.
