Influence of correlation effects on the excitonic semiconductor photoluminescence

Abstract

The influence of higher-order Coulomb effects on semiconductor luminescence spectra is discussed within a correlation-function approach leading to the semiconductor luminescence equations. The results are compared with a Green's function treatment based on the Bethe-Salpeter equation and the Kubo-Martin-Schwinger relation between absorption and luminescence spectra under equilibrium and steady-state conditions.
