Paper Abstract

A brief review is given of Raman scattering from bound electrons and holes in semiconductor superlattices. The experiments on Si (donor)-doped and Be (acceptor)-doped GaAs/AlGaAs quantum-well structures include studies of the dependence of the energy levels on the position of the impurity in the well and the well-width, and as a function of temperature, magnetic field and uniaxial stress. The data, showing reasonable agreement with theoretical predictions, reveal most of the expected features of quantum confinement effects on the impurity spectra. An extensive list of references to theoretical and related experimental work is included.
