Popis: Dense electron plasmas in modulation-doped GaInAs/AlInAs single quantum well structures have been studied with magnetoluminescence at 2 K. An electron-sheet-concentration ( n s )-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 n s decreases, which is contrary to the results obtained for an electron-hole plasma in GaInAs/InP quantum well.
