Monochromatic cathodoluminescence (CL) imaging of metal-organic vapour phase epitaxy (MOVPE) grown In(0.1)Ga(0.9)N single quantum wells (QW) has been performed in a scanning transmission electron microscope (STEM). Spatially resolved fluctuations in the CL emission wavelength and intensity of the QW luminescence were recorded. The presence of regions with luminescent features asymmetrically distributed either side of the QW peak emission was inferred. These fluctuations may be attributed to, by for example, variations of ±0.01 in the In fraction of the In(0.1)Ga(0.9)N alloy, to changes of up to 0.6nm in the QW thickness. However these factors do not explain the gross fluctuations in QW emission intensity observed in TEM-CL on the scale of approximately one micron.
