Abstract
The dominant role of the strong electron-hole Coulomb correlations in widegap II-VI semiconductor quantum well heterostructures is illustrated by selectively highlighting key phenomena studied in experiments encompassing ZnSe-based QWs. These include gain and stimulated emission at low temperatures from excitonic molecules, excitonic enhancements to gain in room temperature green-blue diode lasers, and light-matter interaction in vertical microcavity lasers.
