Influence of symmetry and Coulomb correlation effects on the optical properties of nitride quantum dots
The electronic and optical properties of self-assembled $\mathrm{In}\mathrm{N}∕\mathrm{Ga}\mathrm{N}$ quantum dots (QDs) are investigated by means of a tight-binding model combined with configuration-interaction calculations. Tight-binding single-particle wave functions are used as a basis for computing Coulomb and dipole matrix elements. Within this framework, we analyze multiexciton emission spectra for two different …
