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 …

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

Since its discovery in less than five years ago, graphene has become one of the hottest
frontiers in materials science and condensed matter physics, as evidenced by the …

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) …

We present first-principles calculations of quantum transport in chemically doped graphene
nanoribbons with a width of up to 4 nm. The presence of boron and nitrogen impurities is …

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 device for the generation of valley polarized electronic current in bilayer
graphene. By analyzing the response of this material to intense terahertz frequency light in …

Electric transport of a zigzag graphene nanoribbon through a steplike potential and a barrier
potential is investigated by using the recursive Green's function method. In the case of the …
