High-frequency breakdown of the integer QHE in GaAs/AlGaAs heterojunctions
V. Dziom, A. Shuvaev, A. V. Shchepetilnikov +3
The integer quantum Hall effect is a well-studied phenomenon at frequencies below about 100 Hz. The plateaus in high-frequency Hall conductivity were experimentally proven to retai…

Direct observation of energy spectrum transition in narrow AlAs quantum wells
A. R. Khisameeva, A. V. Shchepetilnikov, V. M. Muravev +8
Spectra of magnetoplasma excitations have been investigated in a two-dimensional electron systems in AlAs quantum wells (QWs) of different widths. The magnetoplasma spectrum have b…
