Abstract

The electron-LO phonon interaction in Al_xGa_1-xAs has been studied, for the alloy composition ranging from 0.1 to 0.4, by picosecond Raman spectroscopy. We have found that the relative strength of the Frohlich interaction of the two LO phonon modes is a nonlinear function, and increases non- monotonically with the Al composition. The possible origins of these novel results are discussed in term of nonlinear dielectric theory and ordering in the alloy.
