FIG. 1.

(Color online) The QD geometry is shown from atop. The structure is visualized and isosurfaces of the charge density for the three energetically lowest electron (left) and hole (right) states are included for 10% (blue) and 50% (red) of the maximum value. For the holes, the atomistic structure of the wurtzite crystal becomes most apparent for the excited states. The corresponding energies of electron and hole states measured from the valence-band maximum of bulk GaN and the atomic orbital character for each wave function are given. The dominant contributions are highlighted.

(Color online) Emission spectra for a quantum dot with different number of excitons, with (solid line) and without (dashed line) piezoelectric field. Initial states are ground states with total spin component .
