| Outline of Final Research Achievements |
We realize the spin state control of graphene to obtain ultra-low power / functional devices. Graphene is employed as the platforms of spin state control because of small spin-orbit interaction. The key for the spin state
control is the introduction of paramagnetic impurities. The fluorine impurity controlled the charge and spin current in graphene and we call diamond-sheet. Magnetotransport measurements suggests that spin relaxation time could be controllable by one order of magnitude by gate voltages.
We have also tried to observe spin Hall effect using non-local resistance measurement of Hallbar device. We found the possibility of the existence of spin Hall effect in diamond-sheet. Further evidence should be provided in the future by using highly sensitive magnetic sensor consists of NV centers in diamond.
