Abstract

Summary form only given. Quantum well secondary emission (SE) is caused by the radiative decay of excitonic polarization that was scattered at least once after optical excitation. Disorder scattering leads to coherent SE displaying a speckle pattern whereas phonon scattering and Coulombic interaction result in incoherent emission. Presently, most calculations of SE only address a single scattering mechanism. We present a microscopic theory including both phonon and disorder scattering which are the dominant scattering mechanism in the low density regime and consistently include all quantities up to the level of exciton densities. To demonstrate the main features, we show in the following some model calculations for a GaAs/AlGaAs structure.
