Outline of Final Research Achievements

In this project, we aimed mainly at describing energy transfer and dissipation at a single molecule level with a photon-STM. For accomplishing this, we set two main technical goals; improvement of STM luminescence spectroscopy technique and development of THz-STM spectroscopy that can detect photons in THz region from a single molecule. Finally, we report our achievements, such as (1) Measurement of hyperfine luminescence spectra from a single molecule, (2) Development of a novel single-molecule absorption spectroscopy, (3) Real space observation of energy transfer between two molecules, and (4) Development of THz-STM luminescence spectroscopy, which exceeds initial expectations when this project was proposed.
