Transparent Flexible Organic Transistors Based on Monolayer Graphene Electrodes on Plastic

Abstract

Transparent, flexible carbon‐based pentacene field‐effect transistors (FETs) were successfully fabricated from monolayer graphene electrodes on plastic substrates. One‐atom‐thick monolayer graphene provides an ideal material for source/drain electrodes for efficient charge injection and transport, resulting in low contact resistance between the electrodes and the pentacene films. Thus, pentacene FETs with patterned graphene electrodes exhibit significantly higher performances than those of common metal electrodes.

Raman spectroscopy study on the reactions of UV-generated oxygen atoms with single-layer graphene on SiO2/Si substrates

“…Since the preparation of the samples includes polymer-supported transfer involving etching Cu foils, however, the resulting graphene transferred onto SiO 2 /Si substrates contains polymer residues and other contaminants [25]. Thus it is of importance to assess whether or not the inevitable surface contaminants interfere with the photoreactions.…”

Synthesis and applications of graphene electrodes

“…Such devices present high optical transmittance and mechanical bendability. The low contact resistance between graphene and organic materials makes graphene an ideal electrode material, especially in flexible organic field-effect transistors [74][75][76][77][78]. Another kind of graphene-based flexible transistor utilizes graphene as an active channel (Fig.…”

“…[1][2][3] It is all due to its unique physicochemical properties with high surface area, strong mechanical strength, excellent electrical, thermal and optical properties, 4 as well as its potential uses in electronics, [5][6] energy materials, [7][8][9][10] environmental remediation, [11][12][13][14][15] and bioapplications. [16][17][18][19][20][21] Fluorescent graphene complexes have attracted more attention because of their promising nanoscale applications, while the photoluminescence properties of graphene complexes can be realized by functionalizing graphene with fluorescent materials [22][23][24][25][26] through covalent or non-covalent interactions.…”
