Abstract
We present and test a modified thermionic emission model for time-resolved charge-carrier transport perpendicular to the layers of multiple quantum-well structures in an electric field. The predictions of the model on the nature (Gaussian transport) and the dynamics (transport times, field dependence of the mobility) of carrier transport agree favorably with our experiments performed for the case of holes and allow an accurate determination of the band offset.Keywords
