We study the "hybrid" heterostructure formed by one sheet of single-layer graphene (SLG) and one sheet of bilayer graphene (BLG) separated by a thin film of dielectric material. In general, it is expected that interlayer interactions can drive the system to a spontaneously broken-symmetry state characterized by interlayer phase coherence. The peculiarity of the SLG-BLG heterostructure is that t...

An anticorrosion layer is a significant component that prevents the corrosion process in materials. In this work, nanofiber of poly (methyl methacrylate) composited with few-layer-graphene was prepared as an layer. electrospinning applied to prepare composite on metal substrate at various concentrations few-layer graphene. The physical properties were investigated field-emission scanning electr...

Graphene, an atomically thin sheet consisting of only one layer of carbon atoms, attracts intensive research interest since its recent discovery [1], not only due to the simple fabrication process and its unique electronic properties, but also because of the ultimate mechanical strength as well [2], especially for nanoelectromechanical system (NEMS) applications. Here we report the preparation ...

Water transport through graphene-derived membranes has gained much interest recently due to its promising potential in filtration and separation applications. In this work, we explore water permeation in graphene oxide membranes using atomistic simulations and theoretical analysis, by considering flow through the interlayer gallery, expanded channels such as wrinkles of interedge spaces, and po...

Post-growth transfer and high growth temperature are two major hurdles that research has to overcome to get graphene out of research laboratories. Here, using a plasma-enhanced chemical vapour deposition process, we demonstrate the large-area formation of continuous transparent graphene layers at temperatures as low as 450 °C. Our few-layer graphene grows at the interface between a pre-deposite...

A simple method for the deposition of noble metal (Pd, Au) nanoparticles on a free-standing chemical vapour deposited graphene (CVD GR) monolayer is reported. The method consists of assembling the high purity CVD GR, by transfer from poly (methyl methacrylate) (PMMA), at the organic/water interface. Metal deposition can then proceed using either spontaneous or electrochemically-controlled proce...

We have clearly discriminated the single-, bilayer-, and multiple-layer graphene (<10 layers) on Si substrate with a 285 nm SiO2 capping layer by using contrast spectra, which were generated from the reflection light of a white light source. Calculations based on Fresnel's law are in excellent agreement with the experimental results (deviation 2%). The contrast image shows the reliability and e...

Here we report a wafer-scale graphene/P(VDF-TrFE)/graphene multilayer for light-weight, flexible and fast-switched broadband modulation applications. The P(VDF-TrFE) film not only significantly reduces the sheet resistance of graphene throughout heavy doping of ∼0.8 × 10(13) cm(-2) by nonvolatile ferroelectric dipoles, but also acts as an efficient electro-optic (EO) layer. Such multilayered st...

We report a kind of electric field tunable transparent and flexible capacitor with the structure of graphene-Bi1.5MgNb1.5O7 (BMN)-graphene. The graphene films with low sheet resistance were grown by chemical vapor deposition. The BMN thin films were fabricated on graphene by using laser molecular beam epitaxy technology. Compared to BMN films grown on Au, the samples on graphene substrates show...

A single graphene sheet, when subjected to a perpendicular static magnetic field, provides a Faraday rotation that, per atomic layer, greatly surpasses that of any other known material. In continuous graphene, Faraday rotation originates from the cyclotron resonance of massless carriers, which allows dynamical tuning through either external electrostatic or magneto-static setting. Furthermore, ...
