“…[ 103 ] To make patterned rGO electrodes, oxygen plasma etching can be applied to an rGO fi lm with a shadow mask. [ 197 ] Our group developed an alternative method by simply using a sharp nonmetal object to directly scratch rGO fi lms. By mounting the nonmetal object on a micromanipulator, which controlled the movement of the object, the regular rectangular-shaped rGO patterns have been produced.…”

Graphene, the thinnest two dimensional carbon material, has become the subject of intensive investigation in various research fields because of its remarkable electronic, mechanical, optical and thermal properties. Graphene-based electrodes, fabricated from mechanically cleaved graphene, chemical vapor deposition (CVD) grown graphene, or massively produced graphene derivatives from bulk graphite, have been applied in a broad range of applications, such as in light emitting diodes, touch screens, field-effect transistors, solar cells, supercapacitors, batteries, and sensors. In this Review, after a short introduction to the properties and synthetic methods of graphene and its derivatives, we will discuss the importance of graphene-based electrodes, their fabrication techniques, and application areas.

“…Furthermore, in combination with metals, graphene could be also used as an interfacial layer to engineer the charge transfer between metal contacts and other carbon-based systems [16]. More generally, graphene as an electrical contact has been proven to be a superior solution in various electronics applications from organic field effect transistors [17][18][19][20][21][22][23], organic solar cells [24], organic light emitting diodes [25] to nanoelectromechanical infrared detectors [26], and electrophysiology and neuroimaging [27,28]. In addition to electronics, biosensors [29] and biomedical applications such as point-of-care testing devices [30] use graphene to improve analytical performances.…”

Abstract:We used large area, monolayer graphene epitaxially grown on SiC (0001) as contact electrodes for polymer nanofiber devices. Our fabrication process, which avoids polymer resist residues on the graphene surface, results in graphene-polyaniline nanofiber devices with Ohmic contacts and electrical conductivity comparable to that of Au-nanofiber devices. We further checked the thermal stability of the graphene contacts to polyaniline devices by annealing up to T = 800 • C, the temperature at which polyaniline nanofibers are carbonized but the graphene electrode remains intact. The thermal stability and Ohmic contact of polymer nanofibers are demonstrated here, which together with the chemical stability and atomic flatness of graphene, make epitaxial graphene on SiC an attractive contact material for future all-carbon electronic devices.

“…[8] Proposed patterning methods include lithography, [9,10] transfer printing, [11,12] plasma etching, [13,14] and electrocatalysis. [15] Much of the recent work has focused on graphene and includes lithographic patterning of graphene nanoribbons, which are quasi-1D structures with unique charge transport properties [16] and high thermal conductivity [17] that show promise for the development of next-generation electronic devices.…”
