TL;DR: In this paper, it was shown that the intensity attenuation of interband transitions that have those states as their initial or final states is attenuated (Pauli blocking) and when carriers are injected into localized states near the surface of the dots, the electrostatic field set up by these charges attenuates all optically allowed interband transition.

TL;DR: In this paper, the authors discuss the existence of two types of resonant states within this continuum in self-assembled dots: (i) virtual bound states, which characterize square wells even without strain and (ii) strain-induced localized states.

TL;DR: In this paper, a detailed theoretical study of the internal electronic structure of various multiexcitons was performed, where the number of holes and number of electrons in the self-assembled semiconductor quantum dots (QDs).

TL;DR: In this paper, large supercell valence force field simulations are used to investigate the nearest-neighbor bond-length distribution in relaxed tetrahedral (zinc blende and wurtzite) and octahedral (rocksalt) alloys.

TL;DR: In this paper, the authors calculate electron and hole addition energies of PbSe quantum dots using a pseudopotential configuration-interaction approach and find that the addition energies are nearly constant for the first eight carriers occupying the $S$-like shell.
