Scientists create fully electronic 2-D spin transistors

Nanowerk  September 17, 2019 Using gold electrodes, researchers in the Netherlands were able to send a pure charge current through graphene and generate a spin current, referred to as the Rashba-Edelstein effect. This happens due to the interaction with the heavy atoms of the TMD monolayer (in this case, tungsten disulfide). The charge current induces a spin current in the graphene, which they could measure with spin-selective ferromagnetic cobalt electrodes. The charge-to-spin conversion makes it possible to build all-electrical spin circuits with graphene. They showed that the efficiency of the generation of the spin accumulation can be tuned by the […]
