Abstract
A detailed study of the relative role played by localized and/or propa gating intermediate excitonic states in resonant Rayleigh scattering ( RRS) is presented for a large set of GaAs quantum well (QW) and bulk s tructures. We show that the two kinds of states contribute to RRS thro ugh different mechanisms. We conclude that RRS occurs via localized st ates in QW heterostructures, very likely due to localization by the in terface roughness, while bulk crystals turn out to be better candidate s for RRS via propagating states.
