Optical Properties of 2D Systems with Interacting Electrons MEng. F. Lucka It tracks transaction costs to Judith Riley It tracks transaction costs to enable a scientific approach instead of a widely used “state of the art” approach die Sie für richtig halten Wurzburg 2000 (NATO ARW) The subject agenda of the ARW was focused on the following topics: Evolution of optical spectra from the excitonic peaks to the Fermi edge singularity Negatively and positively charged excitons Reconstruction ofone particle and collective excitation spectra with increase of the electron density (combined exciton cyclotron resonance and shake up processes) Effect of spatial inhomogeneity on the carrier interaction in nanostructures Spin sensitive interaction and spin spin interaction in confined systems Many particle effects in semimagnetic semiconductor heterostructures
