Ratchet effects induced by terahertz radiation in heterostructures with a lateral periodic potential
P. Olbrich, E. L. Ivchenko, T. Feil +5
We report on the observation of terahertz radiation induced photogalvanic currents in semiconductor heterostructures with one-dimensional lateral periodic potential. The potential…
Phase coherent transport in (Ga,Mn)As
D. Neumaier, K. Wagner, U. Wurstbauer +3
Quantum interference effects and resulting quantum corrections of the conductivity have been intensively studied in disordered conductors over the last decades. The knowledge of ph…
Symmetry and spin dephasing in (110)-grown quantum wells
V. V. Bel'kov, P. Olbrich, S. A. Tarasenko +7
Symmetry and spin dephasing of in (110)-grown GaAs quantum wells (QWs) are investigated applying magnetic field induced photogalvanic effect (MPGE) and time-resolved Kerr rotation.…
Weak localization in ferromagnetic (Ga,Mn)As nanostructures
D. Neumaier, K. Wagner, S. Geissler +4
We report on the observation of weak localization in arrays of (Ga,Mn)As nanowires at millikelvin temperatures. The corresponding phase coherence length is typically between 100 nm…
Tunneling anisotropic magnetoresistance and spin-orbit coupling in Fe/GaAs/Au tunnel junctions
J. Moser, A. Matos-Abiague, D. Schuh +3
We report the observation of tunneling anisotropic magnetoresistance effect (TAMR) in the epitaxial metal-semiconductor system Fe/GaAs/Au. The observed two-fold anisotropy of the r…
