Abstract :
In this study, we investigated the optical characteristics of single charge-tunable InAs QDs emitting at 1.2 μm, whose size is about twice those discussed in the previous reports. For probing electronic shell structures, large QDs are favorable in terms of deep confinement potentials and weak Coulomb interaction.
