| Outline of Final Research Achievements |
Silicon (Si) spintronics is becoming a pivotal field in semiconductor spintronics. Si is a light element and its crystal structure possesses a spatial inversion symmetry, which enable good spin coherence. Furthermore, Si spintronics devices have good compatibility with existing Si-LSI(large scale integration ) technologies. In this study, we investigated manipulation of a spin current in Si at room temperature. By applying perpendicular magnetic field spin precession more than 4 π was realized. Furthermore, long spin transport more than 21 micro meter and gate modulation of the spin transport signals were achieved at room temperature.
