| Outline of Final Research Achievements |
Recently, the spin-orbit interaction (SOI) in hydrogenated graphene (H-graphene) is expected to be enhanced 100 times compared to the pristine graphene due to breaking inversion symmetry. In this study, I verified the enhancement of the SOI by detecting inverse spin Hall effects in H-graphene in order to realize H-graphene spintronics devices. I fabricated spin-injection devices and succeeded in injecting spin currents into H-graphene and detecting inverse spin-Hall effects. The estimated value of the SOI is less than the previous work but clearly enhanced by hydrogenation.
