Abstract
An influence of electron–phonon coupling and electron confinement on optical spectra is studied for donors in semiconductor quantum wells. A binding and 1s–2p transition energies have been calculated by the optimized canonical transformation method for GaAs/AlGaAs, CdTe/CdZnTe, and CdF2/CaF2 quantum wells. We have found that — in the quantum wells made from the ionic semiconductors — the 1s–2p transition energy exceeds the LO-phonon energy and the phonon resonances can appear in the optical spectra of donors. We have estimated the parameters of quantum wells, for which the phonon resonances can be detected in the absence of external magnetic field.
