... between QD and barrier material, the determination of the QD struc- tural properties is affected by much less uncertainties compared to SK QDs. This renders the calculation of the QD optical and electronic ... electronic properties easier [7–10] and makes these QDs an ideal playground to under- stand basic QD properties [11]. Moreover, the size and shape of the QDs can...
