We study GaAs-Al(x)Ga(1−x)As 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.

Abstract
We study GaAs-Al(x)Ga(1−x)As 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.File in questo prodotto:
