Description
Summary:The superradiance model was recently successfully applied to describe semiconductor quantum well luminescence spectra at low temperature (77 K). In the present work, we expand and develop this approach for room-temperature spectra and compare results with optical autocorrelation data obtained earlier. Also, the convenience of the superradiance model has been proven for precise description of cryogenic spectra of quantum dot heterostructures. Numerical analysis of quantum dot spectra allows us to conclude that homogeneous line broadening dominates over inhomogeneous one.
