Abstract :
We study GaAs-AlxGa1−xAs superlattices where the heights of the barriers are modulated by a Gaussian profile. Such structures present bands of almost unscattered electronic states. The calculated energy levels of the superlattice agree well with the photoluminescence spectra recorded at low temperature.
