Scattering of Graphene Plasmons by Defects in the Graphene Sheet [PDF]
ACS Nano, 2013 A theoretical study is presented on the scattering of graphene surface plasmons by defects in the graphene sheet they propagate in. These defects can be either natural (as domain boundaries, ripples and cracks, among others) or induced by an external gate.

Growth mechanism of graphene-skinned glass fibre fabrics driven by various carbon sources
Nano ResearchThe direct growth of graphene via chemical vapour deposition on dielectric materials is a promising approach for transfer-free applications. However, large-scale production using this technique is hindered by the slow growth on non-catalytic substrates ...

Wien effect in interfacial water dissociation through proton-permeable graphene electrodes
Nature Communications, 2022 Direct observation of electric field effects in the water dissociation reaction remains elusive. Here, the authors report an exponential acceleration of the reaction as function of the interfacial electric field using graphene electrodes decorated with ...

High-yield production of graphene by liquid-phase exfoliation of graphite. [PDF]
Nature Nanotechnology, 2008 Fully exploiting the properties of graphene will require a method for the mass production of this remarkable material. Two main routes are possible: large-scale growth or large-scale exfoliation.

Efficient phonon cascades in WSe2 monolayers
Nature Communications, 2021 The primary stages of carrier relaxation in atomically thin transition metal dichalcogenides are hardly accessible due to their fast timescales. Here, the authors measure the first stages of carrier–phonon interaction in monolayer WSe2 via a series of ...

Energy gaps in graphene nanoribbons. [PDF]
Physical Review Letters, 2006 Based on a first-principles approach, we present scaling rules for the band gaps of graphene nanoribbons (GNRs) as a function of their widths. The GNRs considered have either armchair or zigzag shaped edges on both sides with hydrogen passivation.

Graphene–Graphene Interactions: Friction, Superlubricity, and Exfoliation [PDF]
Advanced Materials, 2018 AbstractGraphite's lubricating properties due to the “weak” interactions between individual layers have long been known. However, these interactions are not weak enough to allow graphite to readily exfoliate into graphene on a large scale. Separating graphite layers down to a single sheet is an intense area of research as scientists attempt to utilize ...
