Abstract
A simultaneous determination of both the conduction and valence-band d ispersion curves (and masses) from a single compound semiconductor qua ntum-well structure using magnetoluminescence is discussed. Data from InGaAs/GaAs strained-single-quantum wells and GaAs/AlGaAs lattice matc hed quantum wells are presented. The conduction bands are found to be parabolic for densities approaching 1 x 10(12) cm(-2). However, the va lence bands are highly nonparabolic and strongly affected by heavy-hol e light-hole mixing.
