Deep level transient spectroscopy was used to investigate deep-level defects in (Ga,In)(N,As)/GaAs triple quantum well structures grown by atmospheric pressure metalorganic vapor phase epitaxy with different indium and nitrogen contents and annealed in rapid thermal annealing system. A combination of electron traps that disappear or remain on annealing and a new hole trap that appears on annealing were detected. The revealed electron traps were attributed to N-related complexes or GaAs host-related native point defects. Moreover, it was suggested that the new hole trap observed in the annealed GaAsN/GaAs triple quantum well structure together with the dominant electron trap can act as generation-recombination center responsible for the observed a very poor optical quality among all the investigated multi-quantum well structures.
