The intersubband transitions were completely depleted in samples irradiated with doses as low as 4 × 1014 cm-2. More than 80% recovery of these depleted transitions was achieved after the samples were thermally annealed at temperatures less than 650°C. The total integrated areas and peak position energies of the intersubband transitions in irradiated and unirradiated samples were monitored as a function of annealing temperature. It was noted that the recovery of the depleted intersubband transitions in irradiated samples depend on the irradiation dose and thermal annealing temperature.3English2000-10-3010.1063/1.1320846http://www.scopus.com/inward/record.url?scp=0010752537&partnerID=8YFLogxK
