Figure 1From: Strain analysis for the prediction of the preferential nucleation sites of stacked quantum dots by combination of FEM and APTAPT data of two stacked QDs. (a) APT data obtained from the analysed sample. In atoms are shown as yellow dots and Ga atoms as blue dots. (b,c) Perpendicular In composition slices of the APT data corresponding to the lower QD layer where the In inhomogeneous distribution is showed.Back to article page
