The Singwi–Sjölander–Tosi–Lang approximation to the dielectric response of a 3D electron gas was designed to include exchange and correlation effects. This paper presents the formal extension to a low dimensionality, confined electron gas having a multisubband spectrum of one electron states. The quasi 1D case (quantum wire) is explicitly considered. It is(More)
The absorption coefficient and the photoluminescence of (001) GaN/AlN quantum wells are calculated for several values of the well width, with and without the excitonic effect corrections, in the usual monoelectronic approach and as a many-body problem. The calculation was performed considering separate isolated bands for electrons, heavy and light holes.(More)
The free carrier absorption coefficient of a low dimensional semiconductor system is formulated, with inclusion of interparticle Coulomb interaction, perturbatively, considering the bubble diagrams summed up to infinite order, which accounts for the multisubband (Q2D or Q1D case) or multilevel (Q0D case) electronic structure for reduced dimensionality. The(More)
