RAMAN PROBING OF PHONONS AND INTERFACES IN SEMICONDUCTOR SUPERLATTICES

M. Klein , C. Colvard , R. Fischer , H . Morkoç

Raman measurements on a large number of GaAs-AlxGa1-xAs superlattices are presented. The observed frequencies are in agreement with the model of a layered elastic continuum. A continuum model for the Raman intensities seems valid for the case of nonresonant excitation.
