Graphene
Hybrid heterostructure composed of graphene and perovskite oxide LaCoO3 realizes a novel spintronics device with substantial spin exchange splitting which is tunable by electric gate‐field. The large and tunable spin exchange splitting in graphene is attributed to the charge transfer across the heterointerface. More details can be found in article number 2311287 by Dongseok Suh, Woo Seok...
Graphene, with spin and valley degrees of freedom, fosters unexpected physical and chemical properties for the realization of next‐generation quantum devices. However, the spin‐symmetry of graphene is rather robustly protected, hampering manipulation of the spin degrees of freedom for the application of spintronic devices such as electric gate‐tunable spin filters. It is demonstrated that a hybrid...
