Calculation of conduction-to-conduction and valence-to-valence transitions between bound states in (In,Ga)As/GaAs quantum dots
Gustavo A. Narvaez, Alex Zunger
We have calculated the conduction-to-conduction and valence-to-valence absorption spectrum of bound states in (In,Ga)As/GaAs quantum dots charged with up to three electrons or hole…
Electronic structures of (In,Ga)As/GaAs quantum dot molecules made of dots with dissimilar sizes
Lixin He, Alex Zunger
Using single-particle pseudopotential and many-particle configuration interaction methods, we compare various physical quantities of (In,Ga)As/GaAs quantum dot molecules (QDMs) mad…
Excitonic exchange effects on the radiative decay time of monoexcitons and biexcitons in quantum dots
Gustavo A. Narvaez, Gabriel Bester, Alberto Franceschetti +1
Electron-hole exchange interactions split the exciton ground state into "dark" and "bright" states. The dynamics of those states depends on the internal relaxation time between bri…
Carrier relaxation mechanisms in self-assembled (In,Ga)As/GaAs quantum dots: Efficient P -> S Auger relaxation of electrons
Gustavo A. Narvaez, Gabriel Bester, Alex Zunger
We calculate the P-shell--to-S-shell decay lifetime τ(P->S) of electrons in lens-shaped self-assembled (In,Ga)As/GaAs dots due to Auger electron-hole scattering within an atomistic…
Importance of second-order piezoelectric effects in zincblende semiconductors
Gabriel Bester, Xifan Wu, David Vanderbilt +1
We show that the piezoelectric effect that describes the emergence of an electric field in response to a crystal deformation in III-V semiconductors such as GaAs and InAs has stron…
Nominally forbidden transitions in the interband optical spectrum of quantum dots
Gustavo A. Narvaez, Alex Zunger
We calculate the excitonic optical absorption spectra of (In,Ga)As/GaAs self-assembled quantum dots by adopting an atomistic pseudopotential approach to the single-particle problem…
