FIG. 1.

CL spectrum of a green-light-emitting QW taken at . Phonon replicas are observed at the low-energy side of the peak. This spectrum corresponds to the same region as the CL images in Figs. 2(b)–2(f). The letters b–f in the spectrum indicate the monochromatic energies of those images.

Image of FIG. 2.
FIG. 2.

Direct correlation of QW light emission with the distribution of dislocations. (a) Plan-view TEM collage showing the spatial distribution of threading dislocations. Monochromatic images taken at , with the spatial map of dislocations overlaid, and corresponding to photon energies of (b) , (c) , (d) , (e) , and (f) . CL intensity line profiles taken along the arrows in (d) and (f) are shown in Fig. 3.

Image of FIG. 3.
FIG. 3.

Normalized CL intensity line profiles along the arrows in Figs. 2(d) and 2(f). The peak QW emission [ in Fig. 2(d)] is complementary to the high-energy portion of the emission [ in Fig. 2(f)], with little overlap.

Image of FIG. 4.
FIG. 4.

Cross-section TEM images showing the small surface pits that decorate threading dislocations. Note that the pits nucleate above the QW and do not appear to affect the QW.
