Outline of Final Research Achievements |
If a device that can directly measure the electromagnetic interaction between matter and light at the atomic level is developed, it will undoubtedly become an innovative research tool in many fields such as optical science, surface science, materials science, and biological science. The purpose of this study is to develop a next-generation near-field Raman optical microscope that can observe the structure and vibrational levels of a material surface with atomic resolution, and to elucidate the conditions for such atomic resolution observation. The development of a high-resolution Raman optical microscope will enable us to directly measure the atomic-scale interaction between light and materials, which has been impossible to know until now. The knowledge obtained will facilitate the elucidation of the mechanism of functional expression of optical materials and will greatly advance nanophotonics, which is an extremely important discipline in condensed matter science.
