High Frequency Conductivity in the Quantum Hall Regime
F. Hohls, U. Zeitler, R. J. Haug
We have measured the complex conductivity of a two-dimensional electron system in the quantum Hall regime up to frequencies of 6 GHz at electron temperatures below 100 mK.…

High frequency conductivity in the quantum Hall effect
F. Hohls, U. Zeitler, R. J. Haug +1
We present high frequency measurements of the diagonal conductivity sigma_xx of a two dimensional electron system in the integer quantum Hall regime. The width of the sigma_xx peak…

Phonon emission and absorption in the fractional quantum Hall effect
F. Schulze-Wischeler, U. Zeitler, M. Monka +3
We investigate the time dependent thermal relaxation of a two-dimensional electron system in the fractional quantum Hall regime where ballistic phonons are used to heat up the syst…
