  • Graphene-based TFT comprising nitrogen-doped graphene layer as active layer
    Patent number: 11869945
    Abstract: Disclosed is a high-quality and high-functional graphene-based TFT, including: a gate electrode, a gate insulating layer disposed on the gate electrode; an active layer including a nitrogen-doped graphene layer, on which disposed in a partial region of the gate insulating layer; a first electrode disposed on a region of one side of the active layer; and a second electrode disposed on a region of the other side of the active layer. The present invention allows obtaining the TFT having excellent characteristics by directly growing graphene on a Ti layer, implementing damages with remote plasma, and doping with nitrogen gas to fabricate a graphene active layer.
    Type: Grant
