Unlocking extreme doping and strain in epitaxial monocrystalline silicon
Léonard Desvignes, Dominique Débarre, Ludovic Largeau +8
Hyperdoping, overcoming the solubility limit of dopants in a crystalline semiconductor, is a fertile method for the enhancement of the electrical, structural and optical devices' p…
Relaxation mechanism of GaP grown on 001 Sisubstrates: influence of defects on the growth of AlGaPlayers on GaP/Si templates
Konstantinos Pantzas, Grégoire Beaudoin, Myriam Bailly +7
The mechanical stability of commercial GaP/Si templates during thermal an-nealing and subsequent MOCVD growth of GaP and AlGaP is investigated.Although the GaP layer of the templat…
Optical spectroscopy of two-dimensional layered perovskite
K. Gauthron, J. S. Lauret, L. Doyennette +8
We report on optical spectroscopy (photoluminescence and photoluminescence excitation) on two-dimensional self-organized layers of perovs…
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…
Evolution of the magnetic anisotropy with carrier density in hydrogenated (Ga,Mn)As
Laura Thevenard, Ludovic Largeau, Olivia Mauguin +3
The magnetic properties of (Ga,Mn)As thin films depend on both the Mn doping level and the carrier concentration. Using a post growth hydrogenation process we show that it is possi…
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…
Tuning the ferromagnetic properties of hydrogenated GaMnAs
Laura Thevenard, Ludovic Largeau, Olivia Mauguin +2
Hydrogenation and posthydrogenation annealings have been used as a very efficient tool to tune the hole density over a wide range, at fixed magnetic moment concentration, in thin G…
