Abstract
Data on the temperature dependence of the cathodoluminescence intensity in multiple InGaN/GaN quantum-well structures in the temperature range 80–300 K are reported. Unirradiated structures and structures irradiated with electrons with subthreshold energy are studied. It is shown that, upon irradiation, the temperature dependence becomes weaker. From analysis of the results obtained in this study and previously, it can be suggested that electron irradiation initiates the relaxation of strains produced in quantum wells due to the InGaN-GaN lattice mismatch.
