    摘要: A composition and method for forming a field effect transistor with a stable n-doped nano-component. The method includes forming a gate dielectric on a gate, forming a channel comprising a nano-component on the gate dielectric, forming a source over a first region of the nano-component, forming a drain over a second region of the nano-component to form a field effect transistor, and exposing a portion of a nano-component of a field effect transistor to dihydrotetraazapentacene to produce a stable n-doped nano-component, wherein dihydrotetraazapentacene is represented by the formula: wherein in the dihydrotetraazapentacene chemical structure, each of R1, R2, R3, and R4 can be hydrogen, an alkyl group of C1 to C16 carbons, an alkoxy group, an alkylthio group, a trialkylsilane group, a hydroxymethyl group, a carboxylic acid group or a carboxylic ester group.

    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.
