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 ...

RKKY interaction in gapped or doped graphene
, 2012 In our previous work (E. Kogan, Phys. Rev. B {\bf 84}, 115119 (2011)) we calculated RKKY interaction between two magnetic impurities in pristine graphene using the Green's functions (GF) in the coordinate -- imaginary time representation.

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.

Molecular dynamics simulation of graphene sinking during chemical vapor deposition growth on semi-molten Cu substrate [PDF]
, 2020 Copper foil is the most promising catalyst for the synthesis of large-area, high-quality monolayer graphene. Experimentally, it has been found that the Cu substrate is semi-molten at graphene growth temperatures.

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.
