We use micro-Raman scattering to study the interface (IF) optical phonon in a CdSe self-assembled quantum dot structure. Spatially resolved micro-Raman scattering data obtained from a cleaved edge of a sample shows that the IF phonon is localized at the CdSe dot layer. The intensity of the Raman sca
This paper describes structural and optical investigations of molecular beam epitaxy grown strained ZnSe/(Zn,Cd)Se quantum wells. Strain state, cadmium content, and quantum well layer thickness have a strong influence on the emission energy, which allows a luminescence tuning between 2.25 and 2.50 e
