| Outline of Final Research Achievements |
We have demonstrated that nuclear magnetic resonance signals from semiconductor nano-scale devices can be detected through changes in the conductance of the devices. A quantum dot and a quantum point contact, which are basic components of the mesoscopic systems, were chosen as prototypical nano-scale quantum devices. Using the resistively-detected nuclear magnetic resonance technique, we have studied electron spin dynamics in a quantum dot and magnetization of a quantum point contact which has not been measured otherwise.
