A schematic (left) and an optical image (right) of one of the homoepitaxial fluorinated graphene/graphene spin valve devices. The top layer of graphene is used as a tunnel barrier. It is fluorinated to decouple it from the bottom layer of graphene, which is the spin transport channel. (Photo provided by the Army Research Lab/Released)
