Nonradiative recombination of exciton in solids

In this work nonradiative recombination of a localized exciton in a simple model is studied in an unperturbative way. Depending on details of the linear coupling Hamiltonian to single-mode phonons coupled to a big reservoir of fast modes, different results are obtained. Exponential exciton decay has...

Description
Summary:In this work nonradiative recombination of a localized exciton in a simple model is studied in an unperturbative way. Depending on details of the linear coupling Hamiltonian to single-mode phonons coupled to a big reservoir of fast modes, different results are obtained. Exponential exciton decay has been found just in special situations.
