Abstract
We investigate the fulfilment of the quantum degeneracy criterium in bulk GaAs/AlGaAs heterostructures operated under the superradiant emission generation at room temperature. The e-h density has been evaluated by analysing both spontaneous window emission from above the samples and amplified spontaneous emission radiated from their edges. The maximum experimental value of the phase-space density is 1.31 at
. It is supposed that resonant photons with energies at the band gap establish coherence within the e-h ensemble and facilitate the build-up of a macroscopic wave packet from overlapped wave functions of collectively paired electrons and holes. As a result, the photon-mediated “stimulated” condensation of e-h pairs in phase space can take place at room temperature.
