Spectral maximum in the terahertz photoconductance of a quantum point contact
D. M. Kazantsev, V. L. Alperovich, V. A. Tkachenko +1
The disappearance of the giant terahertz photoconductance of a quantum point contact under the increase in the photon energy, which was discovered experimentally (Otteneder et al.,…
Spectral maximum in photoconductance of a quantum point contact
V. L. Alperovich, D. M. Kazantsev, V. A. Tkachenko
A counter-intuitive disappearance of the giant terahertz photoconductance of a quantum point contact (QPC) under increase in the photon energy, which was discovered experimentally…
Magnetically induced spin-dependent photoemission from p-GaAs(Cs,O) into vacuum
D. A. Orlov, V. L. Alperovich, A. S. Terekhov
A spin-dependent emission of optically oriented electrons from p-GaAs(Cs,O) into vacuum was experimentally observed in a magnetic field normal to the surface. This phenomenon is ex…
