The formation process of CdSe self-assembled quantum dots (SAQDs) was investigated systematically by atomic force microscopy (AFM). Several monolayers (MLs) of CdSe …
Modulation-doped N–AlGaAs (GaAs/InAs/GaAs/InAs)/GaAs-heterostructures with InAs- quantum dots (QDs) have been grown and investigated. Using these structures, modulation …
L'objet de ce doctorat est l'etude des proprietes optiques, et en particulier de la relaxation de l'energie des porteurs dans des structures a boites quantiques d'InAs/GaAs. Le travail …

Using a combination of resonant and non-resonant photoluminescence and photoluminescence excitation spectroscopy we have investigated the carrier relaxation …
In this work, the carrier dynamics and electronic properties of self-organized semiconductor quantum dots are studied by depletion-layer capacitance transient spectroscopy (or deep …
