Symmetry breaking for semiconductor excitons induced by Coulomb coupling between heavy and light holes
Shiue-Yuan Shiau, Benoit Eble, Monique Combescot
Semiconductor excitons are commonly seen as hydrogen atom. This analogy requires a unique hole mass. In reality, this is not so due to the complexity of the semiconductor band stru…
Photocreation of a dark electron-hole pair in a quantum dot
Shiue-Yuan Shiau, Benoit Eble, Valia Voliotis +1
Photon absorption in a semiconductor produces bright excitons that recombine very fast into photons. We here show that in a quantum dot set close to a p-doped reservoir, this absor…
Hyperfine interaction in InAs/GaAs self-assembled quantum dots : dynamical nuclear polarization versus spin relaxation
O. Krebs, B. Eble, A. Lemaître +4
We report on the influence of hyperfine interaction on the optical orientation of singly charged excitons X+ and X- in self-assembled InAs/GaAs quantum dots. All measurements were…
Hole spin dephasing time associated to hyperfine interaction in quantum dots
C. Testelin, F. Bernardot, B. Eble +1
The spin interaction of a hole confined in a quantum dot with the surrounding nuclei is described in terms of an effective magnetic field. We show that, in contrast to the Fermi co…
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…
