  • Patent number: 9362365
    Abstract: Various embodiments are provided for graphite and/or graphene based semiconductor devices. In one embodiment, a semiconductor device includes a semiconductor layer and a semimetal stack. In another embodiment, the semiconductor device includes a semiconductor layer and a zero gap semiconductor layer. The semimetal stack/zero gap semiconductor layer is formed on the semiconductor layer, which forms a Schottky barrier. In another embodiment, a semiconductor device includes first and second semiconductor layers and a semimetal stack. In another embodiment, a semiconductor device includes first and second semiconductor layers and a zero gap semiconductor layer. The first semiconductor layer includes a first semiconducting material and the second semi conductor layer includes a second semiconducting material formed on the first semiconductor layer. The semimetal stack/zero gap semiconductor layer is formed on the second semiconductor layer, which forms a Schottky barrier.

  • Patent number: 5693977
    Abstract: An n-channel field-effect transistor is fabricated utilizing a thin-film fullerene (for example, C.sub.60) as the active element. The fullerene film is deposited onto a device substrate in an ultra-high-vacuum chamber and is thus substantially oxygen-free. Subsequently, while still in the chamber, the fullerene film is encapsulated with a material that is impervious to oxygen.
