Abstract

We show that Raman scattering by coupled plasmon-LO phonons of n-GaAs can be used to study the wavevector- and frequency-dependent dielectric function of the charge carriers. It is found that Landau-damping is induced by finite temperatures and carrier lifetime effects. When Landau-damping effects are negligible the results are well described, to the lowest order in wavevector, by the random phase approximation.
