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 …

Colloidal nanoplatelets (NPLs) are atomically flat, quasi-two-dimensional particles of a
semiconductor. Despite intense interest in their optical properties, several observations …

We present a study of free carrier photogeneration and multicarrier bound states, such as
biexcitons and trions (charged excitons), in semiconducting single-walled carbon …

While ensembles of CdSe nanoplatelets (NPLs) show remarkably narrow
photoluminescence line widths at room temperature, adding a CdS shell to increase their …

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 report transport of electron-hole complexes in semiconductor quantum wells under
applied electric fields. Negatively charged excitons (X–), created by laser excitation of a high …

We compare the photoluminescence spectra of the negatively and positively charged
excitons in GaAs quantum wells. We use a structure which enables us to observe both …

We develop the theoretical formalism and study the formation of valley trions in two-
dimensional monolayers within the framework of a nonrelativistic potential model using the …

We report on magneto-optical studies of ZnSe/(Zn, Mg)(S, Se) quantum wells with n-type
and p-type modulation doping. Negatively and positively charged excitons related to the …

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 …
