Outline of Final Research Achievements

We developed the charge-pumping (CP) electrically detected magnetic resonance (EDMR), and improved its sensitivity. Owing to the improved sensitivity, we successfully performed the CP-EDMR experiments on silicon MOS transistors. The current sensitivity is as low as 103 spins and it is expected that single spin detection is possible by higher frequency (GHz range) operations. We also demonstrated that the energy spectroscopy can be performed by the CP-EDMR.
These results indicated that the developed CP-EDMR allows us to investigate the spin correlation during the CP process.
