It appears at room temperature and above a certain threshold of the excitation current. The spectral feature characterizing dislocation related radiation consists of three peaks at around 0.45 eV. The appearance of the dislocation related peaks in the spectrum goes along with a change in the growth rate of the direct band-to-band luminescence upon increasing of the current through the structure. The observation is consistent with an injection of minority carriers in the p+ and n+ regions of the diode. As the p+ region contains the misfit dislocation rich virtual substrate it becomes a source of dislocation luminescence. (© 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
