Abstract

Using photoluminescence we investigated the properties of quasi-two-dimensional electron-hole plasmas in lattice-matched InGaAs/InP-multi-quantum well structures under quasi-stationary excitation. From the lineshape analysis of the spectra we obtained the plasma parameters and information on the subband structure. From optical transitions between higher subbands we determine the conduction band discontinuity to be 210meV, corresponding to 35% of the total discontinuity.
