| Outline of Final Research Achievements |
We investigated the novel spin phenomena and functionalities based on persistent spin helix state in semiconductor heterostructures. We have achieved the discovery of novel spin manipulation method based on spin-momentum locking, the long spin relaxation time by optically excited potential dimple, long spin transport by drift bias under persistent spin helix state and stabilization of spin wave by using lateral confinement in semiconductor two dimensional electron gas. Towards device application and development of persistent spin helix state in new materials, we further investigated the interface-induced spin orbit interaction in atomic layer materials and epitaxial non-magnetic metal films.
