  • Patent number: 10038060
    Abstract: An n-type metal-oxide-semiconductor (NMOS) transistor comprises a graphene channel with a chemically adsorbed nitrogen dioxide (NO2) layer formed thereon. The NMOS transistor may comprise a substrate having a graphene layer formed thereon and a gate stack formed on a portion of the graphene layer disposed in a channel region that further includes a spacer region. The gate stack may comprise the chemically adsorbed NO2 layer formed on the graphene channel, a high-k dielectric formed over the adsorbed NO2 layer, a gate metal formed over the high-k dielectric, and spacer structures formed in the spacer region. The adsorbed NO2 layer formed under the gate and the spacer structures may therefore attract electrons from the graphene channel to turn the graphene-based NMOS transistor off at a gate voltage (Vg) equal to zero, making the graphene-based NMOS transistor suitable for digital logic applications.
