Abstract: An investigation was made of the electroluminescence spectra of a structure with an In_xGa_1–xN (3 nm thick) quantum well pumped by current pulses of up to 4 kA cm^–2 density at T = 77 and 300 K. Considerable spectral broadening (ΔE = 150 — 200 meV) of nonthermal nature was observed. A preliminary study was made of the stability of this light-emitting structure pumped by high-current pump pulses.
