Modeling of Electrons and Excitons Multiple-Exciton-Generation Dynamics in Silicon Clusters using Many-body Green Function Theory

Abstract

The electrons and excitons multiple exciton generation dynamics in two silicon clusters, or more specifically the inelastic scattering rates of electronic and excitonic states in the two silicon clusters, Si26 and Si46, are calculated using many-body Green function theory.

The significance and novelty of the paper were not addressed. There are a couple of errors about calculations: the excitonic decay rates were computed by solving Eq (11), not based on Eq. (13) that was only an initial guess for the decay rate
