Isolated and "screened" D- centers in quantum wells in high magnetic fields
Dzyubenko A. B. , Sivachenko A. Yu.
The spectra of magneto-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 tested directly experimentally. The changes in the spectra which arise with increasing concentration of free electrons in QWs are discussed.
