Room temperature Optical Orientation of Exciton Spin in cubic GaN/AlN quantum dots
D. Lagarde, A. Balocchi, H. Carrere +5
The optical orientation of the exciton spin in an ensemble of self-organized cubic GaN/AlN quantum dots is studied by time-resolved photoluminescence. Under a polarized quasi-reson…
Exciton Spin Dynamics in Semiconductor Quantum Wells
Thierry Amand, Xavier Marie
In this paper we will review Exciton Spin Dynamics in Semiconductor Quantum Wells. The spin properties of excitons in nanostructures are determined by their fine structure. We will…
Efficient dynamical nuclear polarization in quantum dots: Temperature dependence
B. Urbaszek, P. -F. Braun, X. Marie +4
We investigate in micro-photoluminescence experiments the dynamical nuclear polarization in individual InGaAs quantum dots. Experiments carried out in an applied magnetic field of…
Electron spin quantum beats in positively charged quantum dots: nuclear field effects
L. Lombez, P. -F. Braun, X. Marie +5
We have studied the electron spin coherence in an ensemble of positively charged InAs/GaAs quantum dots. In a transverse magnetic field, we show that two main contributions must be…
