摘要：

We report on Raman spectroscopic investigations of LO-phonon-plasmon modes in doped GaAs1-xPx. Overtones of these coupled modes have been observed using resonant scattering. Their frequency and halfwidth shifts versus free carrier concentration are discussed assuming Wannier-Mott excitons as intermediate states in the scattering process.
