Core-shell nanostructure in a Ge_0.9Mn_0.1 film from structural and magnetic measurements
P. Dalmas de Reotier, E. Prestat, P. Bayle-Guillemaud +8
We have characterized a film of Ge_0.9Mn_0.1 forming self-organized nanocolumns perpendicular to the Ge substrate with high resolution scanning transmission electron microscopy com…
Electrical and thermal spin accumulation in germanium
A. Jain, C. Vergnaud, J. Peiro +15
In this letter, we first show electrical spin injection in the germanium conduction band at room temperature and modulate the spin signal by applying a gate voltage to the channel.…
Interface-driven phase separation in multifunctional materials: the case of GeMn ferromagnetic semiconductor
Emmanuel Arras, Frédéric Lançon, Ivetta Slipukhina +11
We use extensive first principle simulations to show the major role played by interfaces in the mechanism of phase separation observed in semiconductor multifunctional materials. W…
Crossover from spin accumulation into interface states to spin injection in the germanium conduction band
A. Jain, J. -C. Rojas-Sanchez, M. Cubukcu +18
Electrical spin injection into semiconductors paves the way for exploring new phenomena in the area of spin physics and new generations of spintronic devices. However the exact rol…
