R. Cingolani et al., RECOMBINATION MECHANISMS AND LASING IN SHALLOW ZN0.9CD0.1SE ZNSE QUANTUM-WELL STRUCTURES/, Physical review. B, Condensed matter, 49(23), 1994, pp. 16769-16772
Magnetoluminescence spectroscopy of the photopumped stimulated emissio
n, together with systematic photoluminescence studies as a function of
the photogeneration rate, were used to identify the main recombinatio
n mechanisms occurring in shallow Zn0.10Cd0.90Se/ZnSe multiple quantum
wells for blue-green laser applications. Although the main spontaneou
s recombination processes have excitonic character, we found that lasi
ng originates from free-carrier transitions.
