  Local field correction effects on intra-layer inelastic scattering rate of
interacting electrons are theoretically investigated in a coupled-quantum-wells
structure, at finite temperature. At first, temperature dependent dynamic
dielectric function is calculated using random phase approximation (RPA). Then,
local field correction effects are considered in calculations by employing
short-range effects of exchange-correlation holes around electrons. We employ
Hubbard, finite-temperature Hubbard and STLS approximations. Finally,
quasi-particle inelastic scattering rate is calculated using the imaginary part
of the electron self-energy within GW method. The results show that
quasi-particle inelastic scattering rate is reduced, when a local field
correction is employed, at any temperature, wave vector and electron density.
