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 …

Graphene and related materials, such as graphene oxide and reduced graphene oxide,
have come to the forefront of research in electrochemical sensors during recent years. The …

To realize graphene-based electronics, various types of graphene are required; thus,
modulation of its electrical properties is of great importance. Theoretic studies show that …

In this work, nitrogen-doped graphene nanosheets serving as lithium storage materials are
presented. The nitrogen-doped graphene nanosheets were prepared by heat treatment of …

We have investigated the effects of doping on a single layer of graphene using angle-
resolved photoemission spectroscopy. We show that many-body interactions severely warp …

We propose a novel mechanism of flat band formation based on the relative biasing of only
one sublattice against other sublattices in a honeycomb lattice bilayer. The mechanism …

We propose a device to break the valley degeneracy in graphene and produce fully valley-
polarized currents that can be either split or collimated to a high degree in a experimentally …

Improving the ferromagnetism property of graphene materials is particularly important for a
wide range of applications such as spintronics, magnetic memory, and other …

We study a versatile structurally favorable periodic sp 2-bonded carbon atomic planar sheet
with C 4 v symmetry by means of the first-principles calculations. This carbon allotrope is …

Zeolitic imidazolate framework-8 (ZIF-8)-derived N-doped graphene analogous polyhedrons
(ZNGs) obtained via the direct carbonation of ZIF-8 are applied to photocatalytic hydrogen …
