Double island Coulomb blockade in (Ga,Mn)As-nanoconstrictions
S. Geißler, S. Pfaller, M. Utz +4
We report on a systematic study of the Coulomb blockade effects in nanofabricated narrow constrictions in thin (Ga,Mn)As films. Different low-temperature transport regimes have bee…
Shot Noise Induced by Nonequilibrium Spin Accumulation
Tomonori Arakawa, Junichi Shiogai, Mariusz Ciorga +8
When an electric current passes across a potential barrier, the partition process of electrons at the barrier gives rise to the shot noise, reflecting the discrete nature of the el…
All-electrical measurements of direct spin Hall effect in GaAs with Esaki diode electrodes
Markus Ehlert, Cheng Song, Mariusz Ciorga +4
We report on measurements of direct spin Hall effect in a lightly n-doped GaAs channel. As spin detecting contacts we employed highly efficient ferromagnetic Fe/(Ga,Mn)As/GaAs Esak…
Valley-Orbit Photocurrents in (111)-oriented Si-MOSFETs
J. Karch, S. A. Tarasenko, E. L. Ivchenko +5
We demonstrate the injection of pure valley-orbit currents in multi-valley semiconductors and present the theory of this effect. We studied photo-induced transport in -doped (11…
