Luminescence spectra of InGaN/AlGaN/GaN p-n-heterostructures were studied at reverse bias sufficient for impact ionization. There is a high electric field in the active InGaN-layer, and the tunnel component of the current dominates at the low reverse bias. Avalanche breakdown begins at |V th |> 8◊10 V, i.e. ≈3 E g /e. Radiation spectra have a short wavelength edge 3.40 eV, and maxima in the range 2.60◊2.80 eV corresponding to the injection spectra. Mechanisms of the hot plasma recombination in p-n-heterojunctions are discussed.

“…We have not seen room-temperature spectra of GaN-based LEDs at such low currents in the literature. The maxima of the spectra of the blue LEDs move with the current in the range h ω max = 2.57-2.67 eV, in contrast to blue SQW LEDs in which the blue maximum does not shift with the current [3] [4] [5]. There is no additional band in the yellow-green region moving with the voltage at low currents.…”

“…There is no additional band in the yellow-green region moving with the voltage at low currents. Such a band was described as a tunnel band in blue SQW LEDs [5] [6] [7]. The maxima of the spectra of the green LEDs move in the range h ω max = 2.2-2.45 eV, a wider range than in green SQW LEDs…”

“…The parameter E 0 had the value E 0 ≈ 50-60 meV, and changed only slightly with the current, as occurred in the spectra of SQW LEDs [3] [4] [5]. The high-energy sides also have an exponential form, I ~ exp(-h ω /E 1 ).…”

“…A model of radiative recombination in 2D-structures with band tails caused by potential fluctuations was successfully applied to luminescence spectra of LEDs with single quantum wells (SQW) [1] [2] [3] [4] [5] and radiative recombination by tunneling was detected at low currents [3] [4] [5] [6] [7] [8].…”
