Machine learning assisted GaAsN circular polarimeter
A. Aguirre-Perez, R. S. Joshya, H. Carrère +4
We demonstrate the application of a two stage machine learning algorithm that enables to correlate the electrical signals from a GaAsN circular polarimeter with the int…
Electron-nuclear spin dynamics of Ga paramagnetic centers probed by spin dependent recombination: A master equation approach
V. G. Ibarra-Sierra, J. C. Sandoval-Santana, S. Azaizia +8
Similar to nitrogen-vacancy centers in diamond and impurity atoms in silicon, interstitial gallium deep paramagnetic centers in GaAsN have been proven to have useful characteristic…
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…
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…
