Enhancement of the Spin Accumulation at the Interface Between a Spin-Polarized Tunnel Junction and a Semiconductor
M. Tran, H. Jaffres, C. Deranlot +4
We report on spin injection experiments at a Co/AlO/GaAs interface with electrical detection. The application of a transverse magnetic field induces a large voltage drop $Δ…
Strain-Control of the magnetic anisotropy in (Ga,Mn)(As,P) ferromagnetic semiconductor layers
Aristide Lemaître, Audrey Miard, Laurent Travers +6
A small fraction of phosphorus (up to 10 %) was incorporated in ferromagnetic (Ga,Mn)As epilayers grown on a GaAs substrate. P incorporation allows reducing the epitaxial strain or…
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…
Optically probing the fine structure of a single Mn atom in an InAs quantum dot
A. Kudelski, A. Lemaître, A. Miard +4
We report on the optical spectroscopy of a single InAs/GaAs quantum dot (QD) doped with a single Mn atom in a longitudinal magnetic field of a few Tesla. Our findings show that the…
Polariton laser using single micropillar GaAs-GaAlAs semiconductor cavities
Daniele Bajoni, Pascale Senellart, Esther Wertz +4
Polariton lasing is demonstrated on the zero dimensional states of single GaAs/GaAlAs micropillar cavities. Under non resonant excitation, the measured polariton ground state occup…
Magnetic patterning of (Ga,Mn)As by hydrogen passivation
Laura Thevenard, Audrey Miard, Laurent Vila +5
We present an original method to magnetically pattern thin layers of (Ga,Mn)As. It relies on local hydrogen passivation to significantly lower the hole density, and thereby locally…
