Thermal conductivity of semiconductor superlattices: Experimental study of interface scattering
J. -Y. Duquesne
We present thermal conductivity measurements performed in three short-period (GaAs)_9(AlAs)_5 superlattices. The samples were grown at different temperatures, leading to different…
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…
Imaging the antiparallel magnetic alignment of adjacent Fe and MnAs thin films
R. Breitwieser, M. Marangolo, J. Luning +5
The magnetic coupling between iron and alpha - MnAs in the epitaxial system Fe/MnAs/GaAs(001) has been studied at the sub-micron scale, using element selective x-ray photoemission…
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…
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…
X-ray scattering from stepped and kinked surfaces: An approach with the paracrystal model
F. Leroy, R. Lazzari, G. Renaud
A general formalism of X-ray scattering from different kinds of surface morphologies is described. Based on a description of the surface morphology at the atomic scale through the…
