Giant enhancement of spin detection sensitivity in (Ga,Mn)As/GaAs Esaki diodes
Junichi Shiogai, Mariusz Ciorga, Martin Utz +6
We investigate the correlation between spin signals measured in three-terminal (3T) geometry by the Hanle effect and the spin accumulation generated in a semiconductor channel in a…
Nonuniform current density and spin accumulation in a 1 μm thick n-GaAs channel
Bernhard Endres, Mariusz Ciorga, Robert Wagner +6
The spin accumulation in an n-GaAs channel produced by spin extraction into a (Ga,Mn)As contact is measured by cross-sectional imaging of the spin polarization in GaAs. The spin po…
Local spin valve effect in lateral (Ga,Mn)As/GaAs spin Esaki diode devices
Mariusz Ciorga, Christian Wolf, Andreas Einwanger +3
We report on a local spin valve effect observed unambiguously in lateral all-semiconductor all-electrical spin injection devices, employing p+-(Ga,Mn)As/n+-GaAs Esaki diode structu…
