[en] This paper reports a theoretical study on local field correction effects on the temperature-dependent intra-layer inelastic scattering rate of interacting electrons in a coupled-quantum-wells structure. The temperature dependent dynamic dielectric function is calculated using random phase approximation. In order to consider the short-range effects of exchange–correlation holes around electrons, the Hubbard, finite-temperature Hubbard and STLS approximations has been employed. Finally, the quasi-particle inelastic scattering rate is calculated using the imaginary part of the electron self-energy within the GW method. The results suggest that employing a local field correction causes reductions in the quasi-particle inelastic scattering rate of electrons in a coupled-quantum-wells, at any temperature, wave vector and electron density.
