Abstract

Evidence for many body shake-up in the magneto-luminescence spectra of quantum wells is presented. Results for both lattice matched InGaAs-InP and strained layer AlGaAs-InGaAs-GaAs structures, covering a wide range of carrier densities, are presented. In all the structures coupling between shake-up and LO phonon excitations is observed. Strong enhancement of the shake-up satellite of the N e = 1 Landau level (LL) recombination, due to resonant coupling with the N e = 0 LL is presented.
