Monolayer graphene exhibits extraordinary properties owing to the unique, regular
arrangement of atoms in it. However, graphene is usually modified for specific applications …

This article reviews the theoretical and experimental work related to the electronic properties
of bilayer graphene systems. Three types of bilayer stackings are discussed: the AA, AB, and …

Electron–electron interactions play an important role in graphene and related systems and
can induce exotic quantum states, especially in a stacked bilayer with a small twist angle …

Graphene is an atomically thin plasmonic medium that supports highly confined plasmon
polaritons, or nano-light, with very low loss. Electronic properties of graphene can be …

We present a combined experimental and theoretical study of twisted double bilayer
graphene with twist angles between 1° and 1.35°. Consistent with moiré band structure …

We review the electronic properties of bilayer graphene, beginning with a description of the
tight-binding model of bilayer graphene and the derivation of the effective Hamiltonian …

Recent Raman scattering studies in different types of graphene samples are reviewed here.
We first discuss the first-order and the double resonance Raman scattering mechanisms in …

The electronic bandgap is an intrinsic property of semiconductors and insulators that largely
determines their transport and optical properties. As such, it has a central role in modern …

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 …

We theoretically study the optical absorption property of twisted bilayer graphenes with
various stacking geometries and demonstrate that the spectroscopic characteristics serve as …
