Excitons, biexcitons and trions in self-assembled (In,Ga)As/GaAs quantum dots: Recombination energies, polarization and radiative lifetimes versus dot height
Gustavo A. Narvaez, Gabriel Bester, Alex Zunger
We calculate the height dependence of recombination energies, polarization and radiative lifetimes of the optical transitions of various excitonic complexes: neutral excitons (X^0)…
Light-induced metastability in Cu(In,Ga)Se2 caused by VSe-VCu complexes
S. Lany, A. Zunger
Using first-principles total-energy calculations we identify the microscopic origin and the physical mechanism that leads to light-induced metastability and persistent photoconduct…
Can a half-metallic zincblende-type structure be stabilized via epitaxy?
Yu-Jun Zhao, Alex Zunger
The need for spin-injectors having the same zincblende-type crystal structure as conventional semiconductor substrates has created significant interests in theoretical predictions…
Addition spectra of quantum dots: The role of dielectric mismatch
Alberto Franceschetti, Andrew Williamson, Alex Zunger
Using atomistic pseudopotential wave functions we calculate the electron and hole charging energies of InAs quantum dots. We find that the charging energies depend strongly on the…
