Nonlinear helicity anomalies in the cyclotron resonance photoresistance of two-dimensional electron systems
Erwin Mönch, Sophia Schweiss, Ivan Yahniuk +7
Our studies of the cyclotron resonance (CR) photoresistance in GaAs-based two-dimensional electron systems (2DES) reveal an anomalously low sensitivity to the helicity of the incom…
Electric-field modification of interfacial spin-orbit field-vector
L. Chen, M. Gmitra, M. Vogel +7
Current induced spin-orbit magnetic fields (iSOFs), arising either in single-crystalline ferromagnets with broken inversion symmetry1,2 or in non-magnetic metal/ferromagnetic metal…
MIRO-like oscillations of magneto-resistivity in GaAs heterostructures induced by THz radiation
T. Herrmann, I. A. Dmitriev, D. A. Kozlov +12
We report on the study of terahertz radiation induced MIRO-like oscillations of magneto-resistivity in GaAs heterostructures. Our experiments provide an answer on two most intrigui…
Magnetooptical Study of Zeeman Effect in Mn modulation-doped InAs/InGaAs/InAlAs Quantum Well Structures
Ya. V. Terent'ev, S. N. Danilov, H. Plank +10
We report on a magneto-photoluminescence (PL) study of Mn modulation-doped InAs/InGaAs/InAlAs quantum wells. Two PL lines corresponding to the radiative recombination of photoelect…
Spin-polarized electric currents in diluted magnetic semiconductor heterostructures induced by terahertz and microwave radiation
P. Olbrich, C. Zoth, P. Lutz +11
We report on the study of spin-polarized electric currents in diluted magnetic semiconductor (DMS) quantum wells subjected to an in-plane external magnetic field and illuminated by…
Electron g-Factor Anisotropy in Symmetric (110)-oriented GaAs Quantum Wells
J. Hübner, S. Kunz, S. Oertel +6
We demonstrate by spin quantum beat spectroscopy that in undoped symmetric (110)-oriented GaAs/AlGaAs single quantum wells even a symmetric spatial envelope wavefunction gives rise…
Spin polarized electric currents in semiconductor heterostructures induced by microwave radiation
C. Drexler, V. V. Bel'kov, B. Ashkinadze +10
We report on microwave (mw) radiation induced electric currents in (Cd,Mn)Te/(Cd,Mg)Te and InAs/(In,Ga)As quantum wells subjected to an external in-plane magnetic field. The curren…
Electron spin relaxation in bulk GaAs for doping densities close to the metal-to-insulator transition
M. Römer, H. Bernien, G. Müller +3
We have measured the electron spin relaxation rate and the integrated spin noise power in n-doped GaAs for temperatures between 4 K and 80 K and for doping concentrations ranging f…
