The wave vector and frequency-dependent local-fields describing the exchange-correlation effects are obtained within the quantum version of self-consistent field approach. The calculated plasmon dispersions are modified by the dynamic local-fields at intermediate wave vectors (i.e. q to approximately kF). The plasmons are damped outside the single-particle excitation region.EnglishComputational methodsCorrelation methodsDampingDielectric materialsDispersion (waves)Electron transitionsSemiconductor plasmasDouble-layer electron systemsExchange-correlation effectsSelf-consistent field methodSemiconductor quantum wellsArticle10.1016/S0038-1098(00)00424-5
