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 …

The search for topological phases of matter is evolving towards strongly interacting systems,
including magnets and superconductors, where exotic effects emerge from the quantum …

Electronic instabilities at the crossing of the Fermi energy with a Van Hove singularity in the
density of states often lead to new phases of matter such as superconductivity,, magnetism …

Atomic vacancies have a strong impact in the mechanical, electronic, and magnetic
properties of graphenelike materials. By artificially generating isolated vacancies on a …

The electronic structure of graphene causes its charge carriers to behave like relativistic
particles. For a perfect graphene sheet free from impurities and disorder, the Fermi energy …

Two-dimensional carbon, or graphene, is a semimetal that presents unusual low-energy
electronic excitations described in terms of Dirac fermions. We analyze in a self-consistent …

We demonstrate that silicene, a 2D honeycomb lattice consisting of Si atoms, loses its Dirac
fermion characteristics due to substrate-induced symmetry breaking when synthesized on …

Nanoribbons (nanographite ribbons) are carbon systems analogous to carbon nanotubes.
We characterize a wide class of nanoribbons by a set of two integers⟨ p, q⟩, and then …

We report low temperature high magnetic field scanning tunneling microscopy and
spectroscopy of graphene flakes on graphite that exhibit the structural and electronic …

We report the direct observation of Landau quantization in Bi 2 Se 3 thin films by using a low-
temperature scanning tunneling microscope. In particular, we discovered the zeroth Landau …
