Recently, it has been demonstrated that the absorption of moderately doped two-
dimensional semiconductors can be described in terms of exciton polarons. In this scenario …

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 …

Trions and excitons, localized laterally in quantum-dot-like potentials in GaAs quantum
wells, were studied by magnetophotoluminescence spectroscopy as a function of magnetic …

We review the photoluminescence of semiconductor nanostructures in high magnetic fields,
concentrating on the effects of the applied magnetic field on orbital motion (wave function …

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 …

In previous work, we have argued that the optical properties of moderately doped two-
dimensional semiconductors can be described in terms of excitons dressed by their …

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 …

The energy spectra and wave functions of up to 14 interacting quasielectrons (QE's) in the
Laughlin ν= 1 3 fractional quantum Hall (FQH) state are investigated using exact numerical …

We present scanning optical stroboscopic confocal microscopy and spectroscopy
measurements wherein three degrees of freedom, namely, energy, real space, and real …

Electron scattering on both neutral (X) and charged (X−) excitons in quantum wells is
studied theoretically. A microscopic model is presented, taking into account both elastic and …
