Graphene is a one-atom-thick layer of graphite, where low-energy electronic states are
described by the massless Dirac fermion. The orientation of the graphene edge determines …

This brief review discusses electronic properties of mesoscopic graphene-based structures.
These allow controlling the confinement and transport of charge and spin; thus, they are of …

We theoretically propose a switching device that operates at room temperature. The device
is an in-plane heterostructure based on a periodically boron-doped (nitrogen-doped) …

Two-dimensional graphene, carbon nanotubes, and graphene nanoribbons represent a
novel class of low dimensional materials that could serve as building blocks for future …

We investigate charge, valley, and spin transports in a normal/ferromagnetic/normal silicene
junction. We show that the charge, valley, and spin conductances in this junction oscillate …

Bilayer graphene with an interlayer potential difference has an energy gap and, when the
potential difference varies spatially, topologically protected one-dimensional states localized …

We will present a brief overview of the electronic and transport properties of graphene
nanoribbons focusing on the effect of edge shapes and impurity scattering. The low-energy …

The current valleytronics research is based on the paradigm of time-reversal-connected
valleys in two-dimensional (2D) hexagonal materials, which forbids the fully electric …

The influence of carrier density on magnetism in a zigzag graphene nanoribbon is studied in
a π-orbital Hubbard-model mean-field approximation. Departures from half filling alter the …

We propose a nonmagnetic, pseudospin-based version of a spin valve, in which the
pseudospin polarization in neighboring regions of a graphene bilayer is controlled by …
