Isolated and "screened" D- centers in quantum wells in high magnetic fields
The spectra of magnet о-optical transitions of D~ centers in GaAs/GaAlAs quantum wells (QWs) in high magnetic fields are considered. Excellent agreement with the experimental data of Huant et al. for the singlet D~ transitions is found; our predictions for the triplet D~ transitions can be directly experimentally tested. We discuss changes in the spectra which arise with increasing concentration of free electrons in QWs.
