(a) PL spectrum and (b) PLE spectrum detected at 2.2 eV, measured at a temperature of 6 K for the -plane template.
(a) PL spectrum and (b) PLE spectrum detected at the peak of the X2 emission, measured at a temperature of 6 K for the MQW structure.
Bright-field cross-sectional TEM image showing the intersection of BSFs with the MQWs. In order to bring the BSFs into strong contrast, the specimen was tilted in the plane by 30° from the zone axis so that was obtained.
QW width dependence of the X1 and X2 PL peaks, measured at a temperature of 6 K. The energies of the corresponding X1 and X2 features from the PL spectrum of the template are indicated by the continuous and dotted lines, respectively.
