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 …

Abstract Two-dimensional (2D) materials exhibit enhanced physical, chemical, electronic,
and optical properties when compared to those of bulk materials. Graphene demands …

The single-particle and many-body properties of twisted bilayer graphene (TBG) can be
dramatically different from those of a single graphene layer, particularly when the two layers …

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

In this paper we present a paradigmatic tight-binding model for single-layer as well as
multilayered semiconducting MoS 2 and similar transition metal dichalcogenides. We show …

When atomically thin two-dimensional (2D) materials are layered, they often form
incommensurate noncrystalline structures that exhibit long-period moiré patterns when …

Abstract Small-twist-angle (< 2°) bilayer graphene has received extraordinary attention
recently due to its exciting physical properties,,,,,,,,,–. Compared with monolayer graphene …

A recent experiment shows that the K′ K valley degeneracy can be lifted in monolayer WSe
2 deposited on a layered ferromagnetic substrate of CrI 3. In this work, we take a van der …

We calculate the magneto-optical conductivity and electronic density of states for silicene,
the silicon equivalent of graphene, and similar crystals such as germanene. In the presence …

A twisted graphene bilayer exhibits a triangular Moiré pattern in the local stacking, that
smoothly alternates between the three basic types AA′, AB′, and BA′. Under an …
