Monolayer group-VI transition metal dichalcogenides have recently emerged as
semiconducting alternatives to graphene in which the true two-dimensionality is expected to …

We present a microscopic theory of neutral excitons and charged excitons (trions) in
monolayers of transition metal dichalcogenides, including molybdenum disulfide. Our theory …

Strong Coulomb interaction in atomically thin transition metal dichalcogenides makes these
systems particularly promising for studies of excitonic physics. Of special interest are the …

Monolayer molybdenum disulfide (MoS2) has emerged as a model system for studying
many-body physics because the low dimensionality reduces screening leading to tightly …

Electron-trion photoluminescence spectra were measured in undoped high-quality GaAs
quantum wells. The obtained line shape depends on temperature and is asymmetric with a …

A brief review is given of optical studies of doped II–VI quantum wells. The properties of
exciton states, neutral as well as positively and negatively charged, are discussed. A wide …

A consistent density‐matrix approach for the absorption spectra of semiconductor
nanostructures at finite carrier densities is presented that describes both bound and …

The interaction of optically excited excitons in atomically thin semiconductors with residual
do** densities leads to many-body effects which are continuously tunable by external gate …

The hydrostatic pressure influence on the binding energy and on the optical properties
(linear and third nonlinear) associated to the 1 s− 1 p intersubband transition of single …

In this paper, we use a many-body approach to study the absorption spectra of electron-
doped two-dimensional semiconductors. Optical absorption is modeled by a many-body …
