    摘要: Aspects of the invention are directed to a method of forming graphene structures. Initially, a cluster of particles is received. The cluster of particles comprises a plurality of particles with each particle in the plurality of particles contacting one or more other particles in the plurality of particles. Subsequently, one or more layers are deposited on the cluster of particles with the one or more layers comprising graphene. The plurality of particles are then etched away without substantially etching the deposited one or more layers. Lastly, the remaining one or more layers are dried. The resultant graphene structures are particularly resistant to the negative effects of aggregation and compaction.

    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.

    摘要: A graphene-based field effect transistor includes source and drain electrodes that are self-aligned to a gate electrode. A stack of a seed layer and a dielectric metal oxide layer is deposited over a patterned graphene layer. A conductive material stack of a first metal portion and a second metal portion is formed above the dielectric metal oxide layer. The first metal portion is laterally etched employing the second metal portion, and exposed portions of the dielectric metal oxide layer are removed to form a gate structure in which the second metal portion overhangs the first metal portion. The seed layer is removed and the overhang is employed to shadow proximal regions around the gate structure during a directional deposition process to form source and drain electrodes that are self-aligned and minimally laterally spaced from edges of the gate electrode.
