Pseudopotential theory of Auger processes in CdSe quantum dots.

Lin-Wang Wang1, Marco Califano, Alex Zunger, Alberto Franceschetti.   

Abstract

Auger rates are calculated for CdSe colloidal quantum dots using atomistic empirical pseudopotential wave functions. We predict the dependence of Auger electron cooling on size, on correlation effects (included via configuration interaction), and on the presence of a spectator exciton. Auger multiexciton recombination rates are predicted for biexcitons as well as for triexcitons. The results agree quantitatively with recent measurements and offer new predictions.
