Abstract
We report on Raman scattering by intersubband excitations in GaAs-AlAs superlattices which exhibit electric-field domains resulting from seq uential resonant tunneling. In regions where two domains coexist, the scattering intensity varies linearly with the applied voltage. This be havior, consistent with the standard domain picture, can be explained by a model relying on the electric-field dependence of the cross secti on and the domain size.
