Outline of Final Research Achievements

In recent years, development of a single electron transistor fabricated with the nanofabrication technology made it possible to control and measure the single electrons. In the future, this technology can lead to detect the electrochemical reaction at the level of the single molecule, enabling the mechanism of the electrochemical catalyst to be elucidated. In this study, we developed finite frequency measurement with single electron accuracy, which is essential in the measurement of chemical impedance. We also developed an electronics that enables real time detection of the single electrons.
