The Occurrence of the Hall--Instability in Crusts of Isolated Neutron Stars
M. Rheinhardt, D. Konenkov, U. Geppert
In former papers we showed that during the decay of a neutron star's magnetic field under the influence of the Hall--drift, an unstable rise of small--scale field structures at the…
Experimental Separation of Rashba and Dresselhaus Spin-Splittings in Semiconductor Quantum Wells
S. D. Ganichev, V. V. Bel'kov, L. E. Golub +9
The relative strengths of Rashba and Dresselhaus terms describing the spin-orbit coupling in semiconductor quantum well (QW) structures are extracted from photocurrent measurements…
Resonant inversion of the circular photogalvanic effect in n-doped quantum wells
S. D. Ganichev, V. V. Bel'kov, Petra Schneider +7
We show that the sign of the circular photogalvanic effect can be changed by tuning the radiation frequency of circularly polarized light. Here resonant inversion of the photogalva…
Tunneling ionization of deep centers in high frequency electric fields
S. D. Ganichev, I. N. Yassievich, W. Prettl
Experimental and theoretical work on the ionization of deep impurity centers in the alternating terahertz field of high-intensity far-infrared laser radiation, with photon energies…
Monopolar Optical Orientation of Electronic Spins in Semiconductors
S. A. Tarasenko, E. L. Ivchenko, V. V. Bel'kov +8
It is shown that absorption of circularly polarized infrared radiation due to intraband (Drude-like) transitions in n-type bulk semiconductors and due to intra-subband or inter-sub…
