Notes:
In heavily dislocated material (dislocation density of mid-107 cm−2), the low-temperature cathodoluminescence intensity of a sufficiently short-period superlattice comes remarkably close to that of comparison structures grown on low-dislocation material. We attribute this effect to a redistribution of the recombination-active sites along the dislocation cores taking place in the material. The driving force of such redistribution may be electrical or chemical in nature.
