Exciton recombination dynamics in ZnCdSe/ZnSe quantum wells

Abstract:

We present results of time-resolved luminescence experiments performed on Zn0.80Cd0.20Se/ZnSe quantum well laser structures as a function of carrier density and temperature. It is found that in narrow wells, where quantum confinement effects are strong, the luminescence is excitonic over all temperatures at densities up to and above threshold. For wide wells the luminescence is observed to cross over to a bimolecular decay profile at high temperature and density, which corresponds to the formation of a correlated electron-hole plasma.

Time-resolved study of stimulated emission in ZnSe/Zn(S,Se) superlattices

Abstract:

The time evolution of the stimulated emission in ZnSe/Zn(S,Se) superlattices has been studied by picosecond photoluminescence spectroscopy. ?The threshold of the stimulated emission is characterised by a sharp decrease of the transition lifetime from 150 ps to less than 30 ps at a carrier density of about 10(12) cm(-2). While the experimental results are consistent with a stimulated emission process due to excitons, they show no evidence of electron-hole plasma recombination.
