This article reviews the basic theoretical aspects of graphene, a one-atom-thick allotrope of
carbon, with unusual two-dimensional Dirac-like electronic excitations. The Dirac electrons …

Chemically derived graphene oxide (GO) possesses a unique set of properties arising from
oxygen functional groups that are introduced during chemical exfoliation of graphite. Large …

The problem of electron-electron interactions in graphene is reviewed. Starting from the
screening of long-range interactions in these systems, the existence of an emerging Dirac …

The electronic properties of graphene, a two-dimensional crystal of carbon atoms, are
exceptionally novel. For instance, the low-energy quasiparticles in graphene behave as …

An introduction to the transport properties of graphene combining experimental results and
theoretical analysis is presented. In the theoretical description simple intuitive models are …

We report on the micro-Raman spectroscopy of monolayer, bilayer, trilayer, and many layers
of graphene (graphite) bombarded by low-energy argon ions with different doses. The …

We report broadband visible photoluminescence from solid graphene oxide, and
modifications of the emission spectrum by progressive chemical reduction. The data suggest …

A major difficulty in implementing carbon‐based electrode arrays with high device‐packing
density is to ensure homogeneous and high sensitivities across the array. Overcoming this …

Spintronics holds the promise for future information technologies. Devices based on
manipulation of spin are most likely to replace the current silicon complementary metal …

We address the electronic structure and magnetic properties of vacancies and voids both in
graphene and graphene ribbons. By using a mean-field Hubbard model, we study the …
