Abstract :
The incorporation of N in the dilute nitrides (In,Ga)(As,N) has been studied with respect to structural, electronic as well as optical properties. Dominant N-related defects have been detected by deep level transient spectroscopy and Raman scattering. Split-interstitial defects consisting of N aimers are attributed to act as both electron traps and nonradiative recombination centers. The admixture of In into Ga(As,N) strongly influences the bonding of N. The correlated spatial redistribution of In and N in a quantum well structure upon thermal annealing is demonstrated by transmission electron microscopy.
