“…Because the various physicochemical properties of graphene are sensitive to its thickness [3][4][5] , the capability of synthesizing uniform graphene with well-controlled layer numbers has been one of the major challenges in graphene research 6 . Chemical vapour deposition (CVD) has been actively investigated since 2009 for growing graphene on catalytic metal films or foils from gaseous carbon sources at high temperatures [7][8][9][10] . The first CVD graphene was obtained on polycrystalline nickel (Ni) film, which has a small lattice mismatch with graphene 7 .…”

Rational design of a binary metal alloy for chemical vapour deposition growth of uniform single-layer graphene

Controlled growth of high-quality graphene is still the bottleneck of practical applications. The widely used chemical vapour deposition process generally suffers from an uncontrollable carbon precipitation effect that leads to inhomogeneous growth and strong correlation to the growth conditions. Here we report the rational design of a binary metal alloy that effectively suppresses the carbon precipitation process and activates a self-limited growth mechanism for homogeneous monolayer graphene. As demonstrated by an ni-mo alloy, the designed binary alloy contains an active catalyst component for carbon source decomposition and graphene growth and a black hole counterpart for trapping the dissolved carbons and forming stable metal carbides. This type of process engineering has been used to grow strictly singlelayer graphene with 100% surface coverage and excellent tolerance to variations in growth conditions. With simplicity, scalability and a very large growth window, the presented approach may facilitate graphene research and industrial applications.

“…Hence graphene holds potential for transparent conductive films (TCFs) application [50]. Graphene, the fascinating component of TCFs, can be fabricated by several methods: (1) GO-reduced graphene [51][52][53][54][55][56][57]; (2) graphene prepared by sonication of graphite in organic solvents, such as N-methyl-2-pyrrolidone and orthodichlorobenzene [58,59]; and (3) graphene grown on metal substrate by CVD [60][61][62][63]. The large scale productivity and low cost of GO-reduced graphene make it a superior candidate for the fabrication of TCFs.…”

Abstract:Graphene, as an intermediate phase between fullerene and carbon nanotube, has aroused much interests among the scientific community due to its outstanding electronic, mechanical, and thermal properties. With excellent electrical conductivity of 6000 S/cm, which is independent on chirality, graphene is a promising material for high-performance nanoelectronics, transparent conductor, as well as polymer composites. On account of its Young's Modulus of 1 TPa and ultimate strength of 130 GPa, isolated graphene sheet is considered to be among the strongest materials ever measured. Comparable with the single-walled carbon nanotube bundle, graphene has a thermal conductivity of 5000 W/(m·K), which suggests a potential application of graphene in polymer matrix for improving thermal properties of the graphene/polymer composite. Furthermore, graphene exhibits a very high surface area, up to a value of 2630 m 2 /g. All of these outstanding properties suggest a wide application for this nanometer-thick, two-dimensional carbon material. This review article presents an overview of the significant advancement in graphene research: preparation, functionalization as well as the properties of graphene will be discussed. In addition, the feasibility and potential applications of graphene in areas, such as sensors, nanoelectronics and nanocomposites materials, will also be reviewed.

“…Recent synthetic efforts have diverged in a number of different directions. For instance, micromechanical cleavage [6], liquid-phase exfoliation [26,27], reduction of graphene oxide [28,29], chemical vapor deposition (CVD) [30][31][32], carbon segregation [33,34], chemical synthesis [35,36] and deterministic placement [37] have been developed to produce single-layer graphene (SLG) or few-layer graphene (FLG). Current efforts in graphene synthesis are mainly focused on the control of area, structural quality, and number of layers [38].…”

Graphene has unique physical properties, and a variety of proof-of-concept devices based on graphene have been demonstated. A prerequisite for the application of graphene is its production in a controlled manner because the number of graphene layers and the defects in these layers significantly influence transport properties. In this paper, we briefly review our recent work on the controlled synthesis of graphene and graphene-based composites, the development of methods to characterize graphene layers, and the use of graphene in clean energy applications and for rapid DNA sequencing. For example, we have used Auger electron spectroscopy to characterize the number and structure of graphene layers, produced single-layer graphene over a whole Ni film substrate, synthesized well-dispersed reduced graphene oxide that was uniformly grafted with unique gold nanodots, and fabricated graphene nanoscrolls. We have also explored applications of graphene in organic solar cells and direct, ultrafast DNA sequencing. Finally, we address the challenges that graphene still face in its synthesis and clean energy and biological sensing applications.
