Abstract

In this paper the influence of dislocations on the excitonic and donor-acceptor (DA) luminescence spectra of p⁺⁺ layers of GaP:N p⁺⁺-p⁺-n-n⁺ light-emitting diodes and structures has been studied experimentally. The appearance of dislocations is shown to be associated with a high level of layer doping. The presence of dislocations brings about a decrease in the luminescence intensity of excitonic bands, a more considerable decline in the intensity of zero-phonon lines than in that of their phononic replicas, and also the appearance of a new defects - NN₂ complexes and isolated N atoms.
