Many-body phenomena related to electron-hole plasmas or liquids in type-II \(\mathrm{GaAs} / \mathrm{AlAs}\) superlattices grown in (100) and (311) direction are investigated by time-resolved luminescence. The band-gap-renormalization in a (100) superlattice is determined using a luminescence linesh

By dealing with the many-body effects and the valence-band nonparabolicity, we discuss the ground-state energy as a function of the sheet carrier density and the well-width for a quasi-twodimensional quantum well system. The many-body effects due to exchange interaction and Coulomb correlation are e
Studies of shallow donor impurities confined in semiconductor quantum-well (QW) structures are reviewed, concentrating on recent experimental (far infrared spectroscopy) and theoretical investigations of negative donor ions (D Β± Β± ) and the effects of excess electrons on the donor-related transition
The magneto-luminescence energy associated with a recombination of a two-dimensional electron with a hole bound to an acceptor is calculated for n-type modulation-doped GaAs/AIGaAs quantum wells. Many-body interactions among electrons and between electrons and a photo-excited hole are taken into acc
