Picosecond photoluminescence intensity correlation measurements of hot carriers in GaAs/AlxGa1-xAs quantum wells

Journal of Luminescence 59:5 (1994) 303-313

Abstract:

We have measured the energy relaxation of hot carriers in doped and undoped GaAs/AlxGa1-xAs quantum wells by detecting time-resolved hot luminescence using a two-pulse intensity correlation technique. The results are compared with time-dependent intensity correlation functions calculated using a model of energy relaxation by optical phonon interactions which includes non-equilibrium phonon effects. The excellent agreement between calculated and experimental correlation functions shows the great potential of this method in measuring ultrafast relaxation processes. © 1994.

Time-resolved and CW optical studies of MBE-grown ZnTe/GaSb epilayers

Journal of Luminescence 60-61:C (1994) 786-787

Authors:

MJ McNamee, RA Taylor, PA Snow, W Hayes, DE Ashenford, B Lunn

Abstract:

We report optical studies of MBE-grown ZnTe/GaSb. Main impurities and free exciton resonances are determined, and polariton-phonon scattering is observed. We also report time-resolved photoluminescence studies, yielding an estimate of the LO phonon lifetime in ZnTe. © 1994.
