Phosphorous alloying: controlling the magnetic anisotropy in ferromagnetic (Ga,Mn)(As,P) Layers
M. Cubukcu, H. J. von Bardeleben, Kh. Khazen +4
Phosphorous alloying of GaMnAs thin films has been used for the manipulation of the magnetic anisotropies in ferromagnetic Ga0.93Mn0.07As1-yPy layers. We have determined the anisot…
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…
Field-Driven Domain-Wall Dynamics in GaMnAs Films with Perpendicular Anisotropy
Alexandre Dourlat, Vincent Jeudy, Aristide Lemaître +1
We combine magneto-optical imaging and a magnetic field pulse technique to study domain wall dynamics in a ferromagnetic (Ga,Mn)As layer with perpendicular easy axis. Contrary to u…
Controlled light-matter coupling for a single quantum dot embedded in a pillar microcavity using far-field optical lithography
A. Dousse, L. Lanco, J. Suffczynski +7
Using far field optical lithography, a single quantum dot is positioned within a pillar microcavity with a 50 nm accuracy. The lithography is performed in-situ at 10 K while measur…
Photon lasing in a GaAs microcavity: similarities with a polariton condensate
Daniele Bajoni, Pascale Senellart, Aristide Lemaître +1
We study experimentally the lasing regime of a GaAs based microcavity sample under strong optical pumping. The very same sample exhibits the strong coupling regime at low excitatio…
