摘要：
The radiative recombination of electrons from a quasi-two-dimensional electron gas with holes localized on acceptors is investigated. The emission spectra for a single heterojunction are calculated including screening and the dynamical response of the Fermi sea. The line-shape analysis provides unambiguous identification of the Fermi-edge singularity in the emission spectra of the two-dimensional electron gas.
