Stacking-dependent band gap and quantum transport in trilayer graphene [PDF]
, 2011 Graphene is an extraordinary two-dimensional (2D) system with chiral charge carriers and fascinating electronic, mechanical and thermal properties. In multilayer graphene, stacking order provides an important yet rarely explored degree of freedom for ...

Raman Spectrum of Graphene and Graphene Layers [PDF]
Physical Review Letters, 2006 Graphene is the two-dimensional building block for carbon allotropes of every other dimensionality. We show that its electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers. The D peak second order changes in shape, width, and position for an increasing number of layers, reflecting the change in the ...

Chaotic dynamics of graphene and graphene nanoribbons [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2020 We study the chaotic dynamics of graphene structures, considering both a periodic, defect free, graphene sheet and graphene nanoribbons (GNRs) of various widths. By numerically calculating the maximum Lyapunov exponent, we quantify the chaoticity for a spectrum of energies in both systems. We find that for all cases, the chaotic strength increases with

Controlling surface porosity of graphene-based printed aerogels
npj 2D Materials and Applications, 2022 The surface porosity of graphene-based aerogels strongly influences their performance in applications involving mass transfer. However, the factors determining the surface porosities are not well-understood, hindering their application-specific ...

Electrons in bilayer graphene. [PDF]
, 2007 Electrons in bilayer graphene possess an unusual property: they are chiral quasiparticles characterized by Berry phase 2pi. We review the tight-binding model of bilayer graphene which determines the band structure and low-energy quasiparticle properties ...

Graphene overcoats for ultra-high storage density magnetic media
Nature Communications, 2021 The main limitation to the areal storage density of hard disk drives (HDDs) is the thickness of carbon overcoats protecting the disk media. Here,
