摘要：

In this work we show that mixed-crystal vibrations pertaining to AlxGa1-xAs regions with different x provide nearly independent contributions in the calculated back-scattering Raman spectra of AlxGa1-xAs superlattices and modulated alloys. This feature indicates that a dynamical characterization of the Al distribution in these heterostructures is at hand.
