  • Apparatuses with atomically-thin ohmic edge contacts between two-dimensional materials, methods of making same, and devices comprising same
    Patent number: 10910473
    Abstract: Apparatuses comprising a substrate; a monolayer graphene film disposed on at least a portion of the substrate; and a single-layer transition metal dichalcogenide (TMD) disposed only on the substrate and lateral edges of the monolayer graphene film, methods of making the apparatuses, and devices comprising one or more of the apparatuses. The apparatuses have a one-dimensional ohmic edge contact between the monolayer graphene and monolayer semiconducting TMDs.
    Type: Grant
