Hyperfine driven spin relaxation of charge carriers in metal-halide perovskites
Guillaume Lague, Frédérick Bernardot, Mauricio Calvo +6
Spin relaxation of localized charge carriers in semiconductors is primarily governed by hyperfine interaction with the surrounding nuclear spin bath. While this mechanism is well-e…
Hole - Nuclear Spin Interaction in Quantum Dots
B. Eble, C. Testelin, P. Desfonds +7
We have measured the carrier spin dynamics in p-doped InAs/GaAs quantum dots by pump-probe photo-induced circular dichroism and time-resolved photoluminescence experiments. We show…
Inversion of the spin polarization of localized electrons driven by dark excitons
B. Eble, C. Testelin, F. Bernardot +2
The creation of free excitons by absorption of circularly polarized photons, and their subsequent fast capture by donors, is at the origin of the spin polarization of donor-bound e…
Signature of the Overhauser field on the coherent spin dynamics of donor-bound electron in a single CdTe quantum well
C. Testelin, F. Bernardot, G. Karczewski +1
We have studied the coherent spin dynamics in an oblique magnetic field of electrons localized on donors and placed in the middle of a single CdTe quantum well, by using a time-res…
Anisotropic spin splitting of the electron ground state in InAs quantum dots
E. Aubry, C. Testelin, F. Bernardot +2
Photoinduced circular dichroism experiments in an oblique magnetic field allow measurements of Larmor precession frequencies, and so give a precise determination of the electron La…
Enhancement of the electron spin memory by localization on donors in a quantum well
J. Tribollet, E. Aubry, G. Karczewski +4
We present easily reproducible experimental conditions giving long electron spin relaxation and dephasing times at low temperature in a quantum well. The proposed system consists i…
