Spin-Valley Relaxation of Rydberg Excitons
V. Jindal, K. Mourzidis, M. Semina +8
Rydberg excitons, characterized by large spatial extension and reduced electron-hole overlap, must have a spin-valley dynamics different from that of ground state excitons. Here we…
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…
