【 摘 要 】

We study the nonradiative Auger decay of excitons in Cu2O, in which two excitons scatter to an excited electron and hole. The exciton decay rate for the direct and the phonon-assisted processes is calculated from first principles; incorporating the band structure of the material leads to a relatively shorter lifetime of the tripler-state ortho excitons. We compare our results with the Auger decay rate extracted from data on highly degenerate tripler excitons and Base-condensed singlet excitons in Cu2O.
