Electroburning of few-layer graphene flakes, epitaxial graphene, and turbostratic graphene discs in air and under vacuum
Graphene-based electrodes are very promising for molecular electronics and spintronics. Here we report a systematic characterization of the electroburning (EB) process, leading to the formation of nanometer-spaced gaps, on different types of few-layer graphene (namely mechanically exfoliated graphene on SiO2, graphene epitaxially grown on the C-face of SiC and turbostratic graphene discs deposi...
متن کاملSize-selective nanoparticle growth on few-layer graphene films.
We observe that gold atoms deposited by physical vapor deposition onto few-layer graphenes condense upon annealing to form nanoparticles with an average diameter that is determined by the graphene film thickness. The data are well described by a theoretical model in which the electrostatic interactions arising from charge transfer between the graphene and the gold particle limit the size of the...
متن کاملSelective gas transport through few-layered graphene and graphene oxide membranes.
Graphene is a distinct two-dimensional material that offers a wide range of opportunities for membrane applications because of ultimate thinness, flexibility, chemical stability, and mechanical strength. We demonstrate that few- and several-layered graphene and graphene oxide (GO) sheets can be engineered to exhibit the desired gas separation characteristics. Selective gas diffusion can be achi...
متن کاملNanometric Resolved Cathodoluminescence on Few-Layer h-BN Flakes
Hexagonal boron nitride (h-BN) is one of the most promising candidates for light emitting devices in the far UV region, presenting a single strong excitonic emission at 5.8 eV. However, a single line appears only in extremely pure monocrystals that can hardly be obtained only though complex synthesis processes. Common h-BN samples present more complex emission spectra that have been generally a...
متن کاملFe-catalyzed Etching of Graphene and Few-layer Graphene
Fe-catalyzed etching of graphite and few-layer graphene (FLG) has been used to create channels with desired crystalline edges [1,2]. Due to the strong Fe-C interaction, graphene can be etched through either carbon hydrogenation or carbon dissolution into Fe alone. In this work, we investigated the Fecatalyzed etching of graphene and few-layer graphene (FLG) in forming gas (10% H2/90% N2) or N2....
