The spin dynamics in self-organized InAs/GaAs quantum dots have been studied by time-resolved photoluminescence performed under strictly resonant excitation conditions. It is demonstrated that the carrier spins in these nanostructures are totally frozen on the scale of the exciton lifetime.
We report about spatially resolved magneto-optical experiments on a self-assembled InGaAs quantum dot. Using electron beam lithograpy for patterning a metal shadow mask we can isolate a single dot. This allows us to study the optical response of a single dot as a function of excitation power and mag
The influence of local charge separation in self-organized In(Ga)As/GaAs quantum dots (QDs) on the exciton dynamics under resonant excitation of the confined exciton in the first excited state is investigated by time-resolved photoluminescence spectroscopy. The oscillator strength and the relaxation
