Abstract

Dense electron plasmas in modulation-doped GaInAs/AlInAs single quantum well structures have been studied with magnetoluminescence at 2 K. An electron-sheet-concentration (ns)-dependent band-gap renormalization is measured in the magnetic field. The data agree well with those measured at zero magnetic field. A rigid effective-mass increase for electrons with different k-states in the conduction band is observed as the ns decreases, which is contrary to the results obtained for an electron-hole plasma in GaInAs/InP quantum well.
