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…
Giant spin-dependent photo-conductivity in GaAsN dilute nitride semiconductor
A. Kunold, A. Balocchi, F. Zhao +4
A theoretical and experimental study of the spin-dependent photoconductivity in dilute Nitride GaAsN is presented. The non linear transport model we develop here is based on the ra…
Room temperature Giant Spin-dependent Photoconductivity in dilute nitride semiconductors
F. Zhao, A. Balocchi, A. Kunold +6
By combining optical spin injection techniques with transport spectroscopy tools, we demonstrate a spin-photodetector allowing for the electrical measurement and active filtering o…
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…

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…
Dynamic nuclear polarization of a single charge-tunable InAs/GaAs quantum dot
Benoît Eble, Olivier Krebs, Aristide Lemaître +6
We report on the dynamic nuclear polarization of a single charge-tunable self-assembled InAs/GaAs quantum dot in a longitudinal magnetic field of 0.2T. The hyperfine interact…
