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.
In this work we present the results of an electrical and structural characterization of molecular beam epitaxy (MBE) grown InAs/In 0.15 Ga 0.85 As quantum dot (QD) structures having InAs coverages of 2.0 and 3.0 ML that are, respectively, below and above the expected critical value for QD ripening i
