Acesso em: 24 abr. 2023. 0103-9733e- 1678-4448http://repositorio.bc.ufg.br/handle/ri/22418In 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.engAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/Plasmon-LO phonon interactionRPA approachGaAs-AlGaAs rectangular quantum wireThe effects of the plasmon LO phonon interaction on the critical densities of RPA approach in quasi-one-dimensional systemArtigohttps://doi.org/10.1590/S0103-97332006000300042
