The quantum Hall ferromagnet at high filling factors: A magnetic field induced Stoner transition
B. A. Piot, D. K. Maude, M. Henini +7
Spin splitting in the integer quantum Hall effect is investigated for a series of AlGaAs/GaAs heterojunctions and quantum wells. Magnetoresistance measurements are pe…
Photocurrent in nanostructures with asymmetric antidots
M. V. Entin, L. I. Magarill
The steady current induced by electromagnetic field in a 2D system with asymmetric scatterers is studied. The scatterers are assumed to be oriented cuts with one diffusive and anot…
Diffusion and ballistic contributions of the interaction correction to the conductivity of a two-dimensional electron gas
G. M. Minkov, A. A. Sherstobitov, A. V. Germanenko +4
The results of an experimental study of interaction quantum correction to the conductivity of two-dimensional electron gas in AB semiconductor quantum well heterostructures…
Properties of 1D two-barrier quantum pump with harmonically oscillating barriers
M. M. Mahmoodian, L. S. Braginskii, M. V. Entin
We study a one-dimensional quantum pump composed of two oscillating delta-functional barriers. The linear and non-linear regimes are considered. The harmonic signal applied to any…
Interplay of the exciton and electron-hole plasma recombination on the photoluminescence dynamics in bulk GaAs
A. Amo, M. D. Martin, L. Vina +2
We present a systematic study of the exciton/electron-hole plasma photoluminescence dynamics in bulk GaAs for various lattice temperatures and excitation densities. The competition…
Bound states in a 2D short range potential induced by spin-orbit interaction
A. V. Chaplik, L. I. Magarill
We have discovered an unexpected and surprising fact: a 2D axially symmetric short-range potential contains {\it infinite} number of the levels of negative energy {\it if one takes…
