Electrons in a periodic lattice can propagate without scattering for macroscopic distances
despite the presence of the non-uniform Coulomb potential due to the nuclei. Such ballistic …

The electron microscope has been a powerful, highly versatile workhorse in the fields of
material and surface science, micro and nanotechnology, biology and geology, for nearly 80 …

In this paper, we study zigzag graphene nanoribbons with edges reconstructed with Stone-
Wales defects, by means of an empirical (first-neighbor) tight-binding method, with …

We study the influence of different edge types on the electronic density of states of graphene
nanostructures. To this end we develop an exact expansion for the single-particle Green's …

We report magnetotransport measurements in ballistic graphene mesoscopic wires where
the charge carrier mean free path is comparable to the wire width W. Magnetoresistance …

The effect of an orthogonal magnetic field is introduced into a numerical simulator, based on
the solution of the Dirac equation in the reciprocal space, for the study of transport in …

Edge reconstruction modifies the electronic properties of finite graphene samples. We
formulate a low-energy theory of the reconstructed zigzag edge by deriving the modified …

We investigate the fine structure of the edge states energy spectrum for zigzag and armchair
ribbons of graphene in a strong magnetic field. At low energy, the spectra can be described …

Using the continuum model, we investigate the electronic properties of two types of bilayer
graphene (BLG) quantum ring (QR) geometries:(i) An isolated BLG QR and (ii) a monolayer …
