In this paper we focus on the temperature dependence and on a detailed analysis of the interplay between Coulomb effects at Hartree-Fock level, namely: subband shifts, exchange and depolarization shifts to the valence intersubband absorption of III-V semiconductor quantum wells. We show how the tendency of the depolarization to create double peaks in the absorption spectra in the presence of a strongly k-space localized dipole moment can be partially compensated by the other Coulomb corrections considered.
