Popis: InxGa1−xAs/InyAl1−yAs based light‐emitting diodes emitting in the wavelength range 1.7–1.9 μm have been grown nonlattice matched on GaAs. Electroluminescence spectra are measured at 77 K and the injection level dependence has been studied. Mechanisms that broaden the lineshape are discussed. The position of the band gap and the electron temperature are derived by fitting the spectra. Band gap narrowing was observed as a function of the injected carrier density.
