Graphene, a single particle thicker carbon layer with a hexagonal form, was successfully
confined, and the potential electrical impact was observed in 2004. Since a surge in study …

The recent discovery of natural biaxial hyperbolicity in van der Waals crystals, such as α-
MoO3, has opened up new avenues for mid-IR nanophotonics due to their deep …

We present a theory of excitons in gated bilayer graphene (BLG) quantum dots (QDs).
Electrical gating of BLG opens an energy gap, turning this material into an electrically …

In this Perspective article, the reader is introduced to several theoretical methods of
determining the exciton wave functions and the corresponding eigenenergies. The methods …

Biased bilayer graphene (BBG) is an important system for studies of excitonic effects in
graphene-based systems, with its easily tunable band gap. This band gap is governed by an …

Plastic garbage has become a severe environmental issue that is gaining traction. For the
remediation of this waste, various treatment technologies, such as degrading, recycling, and …

We determine the optical properties of gated bilayer graphene quantum dots with trigonal
war** (TW) of single-particle energy spectra. The lateral structure of metallic gates …

We predict here the fine structure of an electrically tunable negatively charged exciton (trion)
composed of two electrons and a hole confined in a gated bilayer graphene quantum dot …

The optical properties of two-dimensional materials are exceptional in several respects.
They are highly anisotropic and frequently dominated by excitonic effects. Dipole-allowed …

Trilayer graphene is receiving an increasing level of attention due to its stacking-dependent
magnetoelectric and optoelectric properties and its more robust ferromagnetism relative to …
