We report the results of a systematic investigation of the stimulated emission in ZnSSe/ZnSe superlattices, by time resolved luminescence and high excitation intensity magnetoluminescence. The stimulated emission is found to have excitation origin from localized states around the thresold, and free-carrier origin at carrier densities well above the phase space filling thresold of the exciton.

Abstract
We report the results of a systematic investigation of the stimulated emission in ZnSSe/ZnSe superlattices, by time resolved luminescence and high excitation intensity magnetoluminescence. The stimulated emission is found to have excitation origin from localized states around the thresold, and free-carrier origin at carrier densities well above the phase space filling thresold of the exciton.File in questo prodotto:
