Abstract
We report here on the study of the optical properties of ZnCdSe-ZnSe q uantum structures elaborated by metal-organic chemical vapour depositi on on GaAs substrates. The band structure of these samples is experime ntally investigated by means of photoluminescence and photoreflectance spectroscopy. This makes clear the relationship between strain, carri er confinement and excitonic effects. We have computed for the first t ime heavy- and light-hole excitons associated with ground and excited states sub-bands, in the context of a self-consistent two-parameter tr ial function.
