我们报道了在（100）和（311）A GaAs表面生长的自组装InAs量子点的光学实验。我们观察到的（100）取向的样品中的发光强度与增加Te覆盖的强烈减少。然而，在（311）A取向的样品中，Te诱导的发光减少要小得多。
We report on optical experiments in self-assembled InAs quantum dots grown on (100) and (311)A GaAs surfaces which were precovered with Te. We observe a strong reduction of the luminescence intensity with increasing Te coverage in the (100)-oriented samples. The Te-induced luminescence reduction is, however, much smaller in the (311)A oriented samples.
