Physical Review B | 2005

Multiband theory of multi-exciton complexes in self-assembled quantum dots

W. Sheng; Shun-Jen Cheng; Pawel Hawrylak

We report on a multiband microscopic theory of many-exciton complexes in self-assembled quantum dots. The single particle states are obtained by three methods: single-band effective-mass approximation, the multiband
