| 英文摘要 | Red-emission at similar to 640 nm from self-assembled in0.55al0.45as/al0.5ga0.5as quantum dots grown on gaas substrate by molecular beam epitaxy (mbe) has been demonstrated. we obtained a double-peak structure of photoluminescence (pl) spectra from quantum dots. an atomic force micrograph (afm) image for uncapped sample also shows a bimodal distribution of dot sizes. from the temperature and excitation intensity dependence of pl spectra, we found that the double-peak structure of pl spectra from quantum dots was strongly correlated to the two predominant quantum dot families. taking into account quantum-size effect on the peak energy, we propose that the high (low) energy peak results from a smaller (larger) dot family, and this result is identical with the statistical distribution of dot lateral size from the afm image. |
