Abstract

Wide-gap II-VI heterostructures provide an excellent opportunity to examine the behavior of dense excitonic systems, with direct implications on blue-green semiconductor lasers. “Recently the role oí excitonic molecules in the formation of gain has been studied in the ZnCdSe¹ and ZnSe² quantum wells at cryogenic temperatures. The binary ZnSe QWs allows the investigation of molecules and excitonic interactions in a high density regime with exceptional spectral clarity; a regime where these transcend a normal perturbative regime.
