| Outline of Final Research Achievements |
We establish the nano-spectroscopic technique for single molecule detection. To achieve this goal, we develop a fabrication process of the surface enhanced Raman scattering (SERS) device based on the precisely controlled nanogap electrodes. In the first year, we developed the fabrication process of the SERS device, and found the effectiveness of the nanogap structure for SERS device by observation of the Raman spectra from the fluorescent molecules. Next, we focused on the multilayer graphene thin films with excellent in flexibility as an electrode. We succeed in synthesizing the highly crystalline multilayer graphene thin films by developing the thermal treatment method at high process temperature above 1000℃ in ethanol vapor. This result indicates that the synthesized multilayer graphene thin films are promising material for the electrode in SERS device. We are now studying further crystallization of the material and compatibility with nanogap formation process.
