Magneto-optical studies of compound semiconductors
A simultaneous determination of both the conduction and valence-band dispersion curves (and masses) from a single compound semiconductor quantum-well structure using magnetoluminescence is discussed. Data from InGaAs/GaAs strained-single-quantum wells and GaAs/AlGaAs lattice matched quantum wells are presented. The conduction bands are found to be parabolic for densities approaching 1 × 1012cm-2. However, the valence bands are highly nonparabolic and strongly affected by heavy-hole light-hole mixing. © 1995.
