Borges Física, Astronomía y Matemáticas GaAs Plasmon RPA Approach LO phonon interaction AlGaAs rectangular quantum wire In this work we have studied the electron LO phonon interaction on the pair-correlation function g(x) and itsdependence on the electronic density for a GaAs-AlGaAs rectangular quantum wire within the random-phaseapproximation (RPA). We assumed two different values of the wire width. As negative non-physical results arefound for lower electronic densities and small interparticle separations in the RPA approach, we have delimitedthe regions where the RPA approach cannot be used for the calculation of the Q1D electron gas collectiveexcitation. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436342 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2A Vol.36
