We have investigated the properties of neutral and charged excitons in single CdSe/ZnSe QD photodiodes by m-photoluminescence spectroscopy. By applying a bias voltage, we have been able to control the number of electrons in a single QD by shifting the energy levels of the QD with respect to the Ferm
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
