Abstract

The observation of a many-body Fermi-energy edge singularity in the low-temperature photoluminescence spectra of InGaAs-InP quantum wells is reported. Strong enhancement of the photoluminescence intensity towards the electron Fermi energy (EFe) is observed, due to multiple electron-hole scattering processes to states above EFe. Recombination of electrons in states up to EFe is allowed by hole localization. The many-body processes are analogous to the core-hole phenomena in the soft-X-ray emission spectra of metals
