Calculation of the biexciton shift in nanocrystals of inorganic perovskites

18 Feb 2020 Nguyen T. P. T. Blundell S. A. Guet C.

We calculate the shift in emission frequency of the trion and biexciton (relative to that of the single exciton) for nanocrystals (NCs) of inorganic perovskites CsPbBr3 and CsPbI3. The calculations use an envelope-function k.p model combined with self-consistent Hartree-Fock and a treatment of the intercarrier correlation energy in the lowest (second) order of many-body perturbation theory...
