Starting from the single-particle Dirac Hamiltonian for charge carriers in monolayer transition
metal dichalcogenides (TMDs), we construct a four-band Hamiltonian describing interlayer …

The emission and absorption spectra of quantum wells containing electron or hole gas are
reviewed. We show that trions, also known as charged excitons, play a dominant role in …

The electronic and structural properties of excitons and trions in monolayer transition metal
dichalcogenides are investigated using both a multiband and a single-band model. In the …

The influence of a perpendicular magnetic field on the binding energy and structural
properties of excitons, trions, and biexcitons in monolayers of semiconducting transition …

A variational calculation of the ground-state energy of neutral excitons and of positively and
negatively charged excitons (trions) confined in a single-quantum well is presented. We …

We study the photoluminescence spectrum of a low-density (ν< 1) two-dimensional electron
gas at high magnetic fields and low temperatures. We find that the spectrum in the fractional …

A theory of charged excitons X− in a dilute two-dimensional (2D) electron gas in a high-
magnetic field is presented. In contrast to previous calculations, three bound X− states (one …

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 organic-inorganic hybrid perovskites show excellent optical and electrical properties for
photovoltaic and a myriad of other optoelectronics applications. Using high-field magneto …

We present a variational calculation of the spin-singlet and spin-triplet states of a negatively
charged exciton (trion) confined to a single quantum well in the presence of a perpendicular …
