Abstract
Dense electron plasmas in modulation-doped GaInAs/AlInAs single quantu m well structures have been studied with magnetoluminescence at 2 K. A n electron-sheet-concentration (n(s))-dependent band-gap renormalizati on is measured in the magnetic field. The data agree well with those m easured at zero magnetic field. A rigid effective-mass increase for el ectrons with different k-states in the conduction band is observed as the n(s) decreases, which is contrary to the results obtained for an e lectron-hole plasma in GaInAs/InP quantum well.
