| Research Abstract |
To obtain information of optical and electric properties of metal-molecule-metal junctions, plasmon resonances of metal nanogap structures have been measured by alternating molecular spacers with different thickness and conductivities. In this project, the gap distance in the nanogap structures was precisely controlled by the use of single crystalline metal substrates. It was experimentally confirmed that the optical property of the metal nanogap system was significantly affected by tunneling effects via the molecular layer.
