abstract = "We report on the controlled transfer of very low electron densities in a single GaAs quantum well from electron hole pairs photoexcited in neighboring narrow quantum wells. Single particle excitation Raman scattering line shapes are in perfect agreement with the Lindhard dielectric function for electron densities well below 1010 cm-2, a density where exchange-correlation is expected to play an essential role in the collective behavior of the electron gas.",
