Evidence for excitonic polarons in InAs/GaAs quantum dots
Vanessa Preisler, Thomas Grange, Robson Ferreira +5
We investigate the interband transitions in several ensembles of self-assembled InAs/GaAs quantum dots by using photoluminescence excitation spectroscopy under strong magnetic fiel…
Bistability of the Nuclear Polarisation created through optical pumping in InGaAs Quantum Dots
P. -F. Braun, B. Urbaszek, T. Amand +5
We show that optical pumping of electron spins in individual InGaAs quantum dots leads to strong nuclear polarisation that we measure via the Overhauser shift (OHS) in magneto-phot…
Magnetic properties and domain structure of (Ga,Mn)As films with perpendicular anisotropy
Laura Thevenard, Ludovic Largeau, Olivia Mauguin +4
The ferromagnetism of a thin GaMnAs layer with a perpendicular easy anisotropy axis is investigated by means of several techniques, that yield a consistent set of data on the magne…
Hole-LO phonon interaction in InAs/GaAs quantum dots
Vanessa Preisler, Robson Ferreira, Sophie Hameau +4
We investigate the valence intraband transitions in p-doped self-assembled InAs quantum dots using far-infrared magneto-optical technique with polarized radiation. We show that a p…
