- 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.
