We have found nonlinearity in the current-voltage characteristics by resonant tunneling of a gold electrode modified with a self-assembled monolayer (SAM) and N719 and cross-linked with gold particles. However, the details of the resonance tunneling mechanism have not been elucidated. In this study, the charge transfer between N719 and Au via SAM was observed by frequency modulation mode atomic force microscopy (FM-AFM) in order to elucidate the mechanism in detail.
