Coulomb Drag as a Probe of the Nature of Compressible States in a Magnetic Field
K. Muraki, J. G. S. Lok, S. Kraus +5
Magneto-drag reveals the nature of compressible states and the underlying interplay of disorder and interactions. At ν=3/2 a clear T^{4/3} dependence is observed, which signifies t…
Magnetic field dependent transmission phase of a double dot system in a quantum ring
M. Sigrist, A. Fuhrer, T. Ihn +4
The Aharonov-Bohm effect is measured in a four-terminal open ring geometry based on a Ga[Al]As heterostructure. Two quantum dots are embedded in the structure, one in each of the t…
Combined atomic force microscope and electron-beam lithography used for the fabrication of variable-coupling quantum dots
M. C. Rogge, C. Fuehner, U. F. Keyser +4
We have combined direct nanofabrication by local anodic oxidation with conventional electron-beam lithography to produce a parallel double quantum dot based on a GaAs/AlGaAs hetero…
Singlet-Triplet Transition Tuned by Asymmetric Gate Voltages in a Quantum Ring
A. Fuhrer, T. Ihn, K. Ensslin +2
Wavefunction and interaction effects in the addition spectrum of a Coulomb blockaded many electron quantum ring are investigated as a function of asymmetrically applied gate voltag…
Spin-galvanic effect due to optical spin orientation
S. D. Ganichev, Petra Schneider, V. V. Bel'kov +13
Under oblique incidence of circularly polarized infrared radiation the spin-galvanic effect has been unambiguously observed in (001)-grown -type GaAs quantum well (QW) structure…
Spin-Galvanic Effect in Quantum Wells
S. D. Ganichev, E. L. Ivchenko, V. V. Bel'kov +6
It is shown that a homogeneous non-equlibrium spin-polarization in semiconductor heterostructures results in an electric current. The microscopic origin of the effect is an inheren…
