| 中文摘要 | in this work we report the optical and microscopic properties of self-organized inas/gaas quantum dots grown by molecular beam epitaxy on (1 0 0) oriented gaas substrates. a distinctive double-peak feature of the pl spectra from quantum dots has been observed, and a bimodal distribution of dot sizes has also been confirmed by scanning tunneling microscopy (stm) image for uncapped sample. the power-dependent photoluminescence (pl) study demonstrates that the distinctive pl emission peaks are associated with the ground-state emission of islands in different size branches. the temperature-dependent pl study shows that the pl quenching temperature for different dot families is different. it is shown that the coupling between quantum dots plays a key role in unusual temperature dependence of qd photoluminescence. in addition, we have tuned the emission wavelength of inas qds to 1.3 mu m at room temperature.
