Our calculations are performed using the self-consistent field approximation, which includes the local-field correction (LFC) within the Singwi, Tosi, Land, and Sjolander (STLS) theory, at zero temperature and assuming a three-subband model, where only the first subband is occupied by electrons. We report for the first time dips in the structure factor spectra as a function of the quasi-one-dimensional (Q1D) plasmon–LO phonon wavevector that are directly related with the resonant split of the collective excitation energy into two branches due to the polaronic effects.engAcesso RestritoArtigo10.1002/pssb.201046242
