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 densities of 1 {times} 10{sup 12} cm{sup {minus}2}. However, the valence bands are highly nonparabolic and strongly affected by heavy-hole light-hole interactions.
