16. Because of the huge bandwidth ( (Formula presented)) of the injector miniband as well as the resonant optical phonon coupling between state (Formula presented) and other injector states, the electron wave packet leaves its initial position in the widest quantum well extremely fast ( (Formula presented)) and loses phase coherence within the time resolution of our experiment.

21. This picture implies a doublet structure of the electroluminescence spectrum. However, the strong broadening of the spectra [see Fig. 1(c)] smears this out
