Resumo
In this work we have studied the electron LO phonon interaction on the pair-correlation function g(x) and its
dependence on the electronic density for a GaAs-AlGaAs rectangular quantum wire within the random-phase
approximation (RPA). We assumed two different values of the wire width. As negative non-physical results are
found for lower electronic densities and small interparticle separations in the RPA approach, we have delimited
the regions where the RPA approach cannot be used for the calculation of the Q1D electron gas collective
excitation.
