The dynamics of intersubband relaxation in GaAs quantum wells and the role of hot carriers and the phonon distributions have been investigated using two different optical techniques with femtosecond resolution: 1) time-resolved photoluminescence and 2) pump and probe experiments. The (2 \(\rightarro
Experimental results on high electric field longitudinal transport in GaAs/AlAs and \(G a A s / G a_{1-x} A l_{x} A s\) multiple quantum wells (MQW) are presented and compared with the prediction of a dielectric continuum model. We draw from our experiments the following four conclusions. (i) In \(
