Influence of In content and QD geometry on the electronic levels. (a) Electronic levels of In_xGa_1−xAs QD with geometry C. (b) Electronic levels of In_0.3Ga_0.7As QDs for the four geometries defined in Figure 2. The Γ electronic level and the heavy-hole level in the QD are calculated with the k·p method. The X and L electronic levels are calculated with the TB model.
