Abstract
We study experimentally and theoretically both vertical transport in the barriers of GaAs/AlGaAs quantum well (QW) heterostructures and the capture of electron-hole pairs into the QWS. By a numerical simulation we determine ambipolar diffusivities, mobilities, surface-recombination velocities, transmission and capture parameters for 40 K 0.5Ga0.5As barriers.Keywords
