Exciton and hole spin dynamics in ZnO
D. Lagarde, A. Balocchi, P. Renucci +7
The carrier spin dynamics in ZnO is investigated by time-resolved optical orientation experiments. We evidence a clear circular polarization of the donor-bound exciton luminescence…
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…
Electrical spin injection into p-doped quantum dots through a tunnel barrier
L. Lombez, P. Renucci, P. Gallo +14
We have demonstrated by electroluminescence the injection of spin polarized electrons through Co/Al2O3/GaAs tunnel barrier into p-doped InAs/GaAs quantum dots embedded in a PIN GaA…
