摘要：
For self-organized quantum dots (QDs) the biexciton binding energy depends strongly on the structural properties. It is demonstrated that even a reversal of the sign can occur for a given QDs ensemble. These findings are significant for single-photon emitters and quantum cryptography utilizing single QDs as it offers a way to the renormalization of the exciton/biexciton level system.
