    摘要： A process comprises combining a Ce (IV) salt with a carbon material comprising CNT or graphene wherein the Ce (IV) salt is selected from a Ce (IV) ammonium salt of a nitrogen oxide acid and is dissolved in a solvent comprising water. The process is conducted under conditions to substantially oxidize the carbon material to produce an oxidized material that is substantially non-conducting. After the oxidation, the Ce (IV) is substantially removed from the oxidized material. This produces a product made by the process. An article of manufacture comprises the product on a substrate. The oxidized material can be formed as a pattern on the substrate. In another embodiment the substrate comprises an electronic device with the oxidized material patterning non-conductive areas separate from conductive areas of the non-oxidized carbon material, where the conductive areas are operatively associated with the device.

    摘要： Graphene transistor devices and methods of their fabrication are disclosed. One such graphene transistor device includes source and drain electrodes and a gate structure including a dielectric sidewall spacer that is disposed between the source and drain electrodes. The device further includes a graphene layer that is adjacent to at least one of the source and drain electrodes, where an interface between the source/drain electrode(s) and the graphene layer maintains a consistent degree of electrical conductivity throughout the interface.
