| Outline of Final Research Achievements |
We developed a nano-spectroscopic method to analyze nano-thermal properties of materials using a laser-illuminated metallic probe tip as a nanoscale heat source. Light induced heating temperature generated in the vicinity of metallic nanostructures was found to be strongly dependent upon the power and wavelength of the incident laser wavelength, and gap distance between two metallic nanostructures as well as size and shape of the metallic nanostructures. The laser-induced temperature increased up to several hundreds °C, which was precisely controlled by the incident laser power. Finally, this technique was successfully applied to investigate glass transition of PMMA polyer thin-films.
