Determination of Trion and Exciton Lineshapes in Modulation-Doped Quantum Wells
J. Berney, L. Schifferle, M. T. Portella-Oberli +1
We investigate the effect of a two dimensional electron gas on the linear optical properties of CdTe quantum wells. We evidence experimentally the high energy tail of the exciton a…
Dynamics of trion formation in GaAs quantum wells
M. T. Portella-Oberli, J. Berney, L. Kappei +3
We propose a double channel mechanism for the formation of charged excitons (trions); they are formed through bi- and tri-molecular processes. This directly implies that both negat…
Light dressed-excitons in an incoherent-electron sea: Evidence for Mollow-triplet and Autler-Townes doublet
Jean Berney, Marcia T. Portella-Oberli, Benoit Deveaud
We demonstrate that the interaction between excitons and a sea of incoherent electrons does not preclude excitons dressing by light. We investigate the role of exciton-electron sca…
