Statistics of Exciton Emission in a Semiconductor Microcavity: Detuning and Exciton-Exciton Effects
We consider the interaction of quantum light with an ideal semiconductor microcavity. We investigate photon statistics in different conditions and the presence of detuning and exciton-exciton interaction. We show that in the resonant interaction and absence of the exciton-exciton interaction, the state of the whole system can be considered as coherent state. According to our results, it turns...
متن کاملExciton-exciton interaction and biexciton formation in bilayer systems
We report quantum Monte Carlo calculations of biexciton binding energies in ideal two-dimensional bilayer systems with isotropic electron and hole masses. We have also calculated exciton-exciton interaction potentials and pair-distribution functions for electrons and holes in bound biexcitons. Comparing our data with results obtained in a recent study using a model exciton-exciton potential Sch...
متن کاملMemory and correlation effects in the exciton-phonon kinetics
The interaction between excitonic and phonon modes in semiconductor nanostructures leads to both relaxation of the excitonic population as well as to pure dephasing of the optical polarization. In small quantum dots, where the interstate relaxation is tiny, clear signatures of pure dephasing effects have been measured, see e.g. the extensive work done in [1] and [2]. In this case, an accurate t...
متن کاملKinetics of exciton photoluminescence in type - II semiconductor superlattices
The exciton decay rate at a rough interface in type-II semiconductor super-lattices is investigated. It is shown that the possibility of recombination of indirect excitons at a plane interface essentially affects kinetics of the exci-ton photoluminescence at a rough interface. This happens because of strong correlation between the exciton recombination at the plane interface and at the roughnes...
متن کاملLow - temperature kinetics of exciton - exciton annihilation of weakly localized one - dimensional Frenkel excitons
We present results of numerical simulations of the kinetics of exciton-exciton annihilation of weakly localized one-dimensional Frenkel excitons at low temperatures. We find that the kinetics is represented by two well-distinguished components: a fast short-time decay and a very slow long-time tail. The former arises from excitons that initially reside in states belonging to the same localizati...
