“…The fascinating properties, which originate from the unique electronic structure of graphene, motivate the wide interest in its potential application in many fields, such as electronics [3][4][5][6][7][8], spintronics [9], optics [5], environmental engineering [10,11], and aerospace [12]. Chemical vapor deposition (CVD) is among the most promising methods for production of macrosize, continuous, high-quality graphene films for industrial applications [13][14][15][16].…”

CVD graphene has attracted a great deal of interest from both academia and industry. The strong motivation to commercialize high quality CVD graphene films and related devices has been restricted by the lack of a cheap, efficient, clean and reliable graphene transfer process. In this article, we report a novel graphene transfer technique which provides a route to high-throughput, reliable and economical transfer of graphene without introducing large cracks and residue contamination from polymers, such as PMMA or magnetic impurities. The transferred graphene was thoroughly characterized with Raman spectroscopy, Atomic Force Microscopy, and X-ray photoelectron spectroscopy. Fabricated large area graphene-based field effect transistors exhibited high mobilities, which were about 2 times higher than those for devices prepared with graphene transferred by the conventional wet transfer method. This new graphene transfer technique has the potential to expedite M

Using multi-functional oxide films, we report on the development of an integration strategy for scalable manufacturing of graphene-based transparent conducting electrodes (TCEs) for organic electronics. A number of fundamental and process challenges exists for efficient graphene-based TCEs, in particular, environmentally and thermally stable doping, interfacial band engineering for efficient charge injection/extraction, effective wetting, and process compatibility including masking and patterning. Here, we show that all of these challenges can be effectively addressed at once by coating graphene with a thin (>10 nm) metal oxide (MoO3 or WO3) layer. We demonstrate graphene electrode patterning without the need for conventional lithography and thereby achieve organic light emitting diodes with efficiencies exceeding those of standard indium tin oxide reference devices.

“…Ex-situ graphene integration techniques 32–35 , such as wet chemical transfer, are the most commonly employed approaches, due to their flexibility of transferring graphene deterministically onto various target surfaces with controlled graphene thickness and integrity. However, such transfer methods are incapable of conformal coating and most often give rise to wrinkles and gaps.…”

Hot electron injection into an exceptionally high mobility material can be realized in grapheneplasmonic nanoantenna hybrid nanosystems, which can be exploited for several front-edge applications including photovoltaics, plasmonic waveguiding and molecular sensing at trace level. Wrinkling instabilities of graphene on these plasmonic nanostructures, however, would cause reactive oxygen or sulfur species diffuse and react with the materials, decrease charge transfer rate and block intense hot-spots. No ex-situ graphene wrapping technique has been explored so far to control these wrinkles. Here, we present a method to generate seamless integration by using water as a flyer to transfer the laser shock pressure to wrap graphene onto plasmonic nanocrystals. This technique decrease the interfacial gap between graphene and the covered substrate-supported plasmonic nanoparticle arrays, by exploiting a shock pressure generated by laser ablation of graphite and water impermeability nature of graphene. Graphene wrapping of chemically synthesized crystalline gold nanospheres, nanorods and bipyramids with different field confinement capabilities are investigated. A combined experimental and computational method, including SEM and AFM morphological investigation, molecular dynamics simulation, and Raman spectroscopy characterization, is used to demonstrate the effectiveness of this technique. Graphene covered gold bipyramid exhibits the best result among the hybrid nanosystems studied. We have shown that the hybrid system fabricated by laser shock can be used for enhanced * Cooresponding authors, gjcheng@purdue.edu; josephi@purdue.edu. + These authors contributed equally.
