Abstract
Our current understanding of elementary electronic excitations in the low-dimensional semiconductor structures (e.g., quantum wells and hetero junctions, multiple quantum wells and superlattices, quantum wires and multiple quantum-wire lateral superlattices) is reviewed with an emphasis on the role of inelastic light scattering spectroscopy in elucidating the elementary excitation spectra. In particular, it is argued that linear response theories based on the random phase approximation give a good account of the existing experimental light-scattering results for the elementary excitation dispersion and spectral weights in GaAs/AlxGa1-xAs-based, two-dimensional electron systems and multilayer superlattices. Theoretical predictions are made about plasmon dispersion in novel structures such as quasi-one-dimensional quantum wires and parabolic quantum wells.KeywordsQuantum WireSpectral WeightElementary ExcitationPlasmon DispersionStrong External Magnetic FieldThese keywords were added by machine and not by the authors.
