Researchers have uncovered a promising new pathway to valleytronics, a potential quantum computing technology in which information is coded based on the wavelike motion of electrons moving through certain 2-D semiconductors.
Graphene has many desirable properties. Magnetism alas is not one of them. Magnetism can be induced in graphene by doping it with magnetic impurities, but this tends to disrupt graphene's electronic properties. Now physicists have found a way to induce magnetism in graphene while also preserving graphene's electronic properties. They have accomplished this by bringing a graphene sheet very close to a magnetic insulator -- an electrical insulator with magnetic properties.
