Spin injection layer
WebApparently, no electromotive voltage signal can be achieved once adding the AlOx layer since spin injection due to FMR was blocked. Spin Hall angle dependence of metallic detector terminal was also undertaken with alternative smallest Cu (bottom of Figure 5d) and smaller Au (bottom of Figure 5e) compared to the standard Pt detector. Observed ... WebThe premise of spintronic device operation is to polarize the carriers spin in the semiconductors. Generally, spin injection methods contain optical injection and electrical injection [ 9, 10 ]. Optical spin injection is a simple and efficient method, but the optical spin injection is not conducive to the device integration.

WebHere, we demonstrate spin injection from a ferromagnetic electrode into a heterojunction based on monolayers of WSe 2 and MoS 2 and lateral transport of spin-polarized holes within the WSe 2 layer. The resulting valley polarization leads to circularly polarized light emission that can be tuned using an external magnetic field.
