Abstract

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.
