FIG. 1.

Absorbance spectra of the intersubband transition in 3 MeV proton irradiated multiple quantum dot samples. The spectra were obtained at room temperature after the samples were irradiated with different doses.

FIG. 2.

Normalized integrated area of the intersubband transition as a function of irradiation dose obtained for multiple quantum dot samples (diamonds), multiple quantum well samples (triangles) and a multiple quantum well samples (circles).

FIG. 3.

Absorbance spectra obtained for a sample irradiated to a fluence of . Spectrum (a) was obtained after irradiation and before furnace thermal annealing, spectrum (b) was obtained after irradiation and after thermal annealing the sample at 500 °C for 15 min, and spectrum (c) was obtained after irradiation and after thermal annealing the sample at 500 °C for 30 min.

Image of FIG. 4.
FIG. 4.

Thermal annealing effect on the absorbance of the intersubband transition in the control sample (unirradiated). Spectrum (a) was obtained before thermal annealing, spectrum (b) was obtained after thermal annealing the sample at 500 °C for 15 min, and spectrum (c) was obtained after thermal annealing the sample at 500 °C for 30 min.
