Optical interband transitions in monolayer transition metal dichalcogenides such as WSe 2
and MoS 2 are governed by chiral selection rules. This allows efficient optical initialization of …

We report charged exciton (trion) formation dynamics in doped monolayer transition metal
dichalcogenides, specifically molybdenum diselenide (MoS e 2), using resonant two-color …

In this work, comprehensive temperature and excitation power dependent
photoluminescence and time-resolved photoluminescence studies are carried out on …

We present a comprehensive examination of optical pumping of spins in individual GaAs
quantum dots as we change the net charge from positive to neutral to negative with a charge …

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 …

The Zeeman splitting and the underlying g factor for conduction-band electrons in Ga As∕
Al x Ga 1− x As quantum wells have been measured by spin-beat spectroscopy based on 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 …

We present a theoretical study combined with experimental validations demonstrating that
CdSe nanoplatelets are a model system to investigate the tunability of trions and excitons in …

Photoluminescence and reflectivity spectra of a high-quality InGaAs/GaAs quantum well
structure reveal a series of ultranarrow peaks attributed to the quantum confined exciton …

We describe theoretically the resonant optical excitation of a trion with circularly polarized
light and discuss how this trion permits the readout of a single electron spin through a …
