Abstract :
Gain/absorption spectra for CdZnSe quantum wells have been simulated at 300 K using a two-transition complex gain function. The incorporation of electron-hole attraction effects into this function causes two exciton-like absorption peaks to appear in the spectra at carrier densities above the Mott density
