| 中文摘要 | in this work we report the photoluminescence (pl) and interband absorption study of si-modulation-doped multilayer inas/gaas quantum dots grown by molecular beam epitaxy (mbe) on (100) oriented gaas substrates. low-temperature pl shows a distinctive double-peak feature. power-dependent pl and transmission electron microscopy (tem) confirm that they stem from the ground states emission of islands of bimodal size distribution. temperature-dependent pl study indicates that the family of small dots is ensemble effect dominated while the family of large dots is likely to be dominated by the intrinsic property of single quantum dots (qds). the temperature-dependent pl and interband absorption measurements are discussed in terms of thermalized redistribution of the carriers among groups of qds of different sizes in the ensemble.
