Theoretical Description of optical properties in III-V Semiconductor Nanostructures — •Marc Landmann, Michal Pochwala, Jens Förstner, Torsten Meier, Eva Rauls, and Wolf Gero Schmidt — Universität Paderborn

We present a joint theoretical study of the optical properties of GaAs and AlAs bulk and heterostructures. Thereby, we compare the theoretical description of optical excitation on several levels of theory. Results obtained from kp theory [1] are discussed along with data from ab initio calculations within the frameworks of independent-particle (DFT), independent quasiparticle (GW), or Coulomb-correlated quasiparticle (BSE) approximation.
