  • Patent number: 10243076
    Abstract: Disclosed is a graphene-based ternary barristor using a Schottky junction graphene semiconductor. A graphene channel layer is doped with N-type and N-type dopants to have two different Fermi levels and form a PN junction. Accordingly, a voltage is applied to a gate electrode layer to move the Fermi levels of the graphene channel layer and adjust the height of the Schottky barrier, thus generating current. Also, the height of the Schottky barrier is adjusted depending on the doping concentration of the graphene channel That is, the height of the Schottky barrier is changed depending on the applied gate voltage, and thus the flow of current is changed. Also, it is possible to adjust the height of the Schottky barrier by adjusting the doping concentration of the graphene channel. Accordingly, since the graphene-based ternary barristor has a high current ratio by adjusting a gate voltage, the graphene-based ternary barristor may be applied to a logic circuit.

    Abstract: Disclosed is a graphene transistor using graphene as a channel region and a logic device using the same. A doping metal layer is provided over a graphene channel of the graphene transistor. The doping metal layer has a work function higher or lower than that of the graphene. When the doping metal layer has a work function lower than that of the graphene, the graphene, which is below the doping metal layer, is doped with an n-type. Also, when the doping metal layer has a work function higher than that of the graphene, the graphene, which is below the doping metal layer, is doped with a p-type. As described above, various aspects of junction may be implemented in the graphene channel, and three states may be obtained from a single transistor.
