Magnetization of a two-dimensional electron gas with a second filled subband
M. R. Schaapman, U. Zeitler, P. C. M. Christianen +5
We have measured the magnetization of a dual-subband two-dimensional electron gas, confined in a GaAs/AlGaAs heterojunction. In contrast to two-dimensional electron gases with a si…
Dynamical scaling of the quantum Hall plateau transition
F. Hohls, U. Zeitler, R. J. Haug +3
Using different experimental techniques we examine the dynamical scaling of the quantum Hall plateau transition in a frequency range f = 0.1-55 GHz. We present a scheme that allows…
Resonant tunneling through zero-dimensional impurity states: Effects of a finite temperature
P. König, U. Zeitler, J. Könemann +2
We have performed temperature dependent tunneling experiments through a single impurity in an asymmetric vertical double barrier tunneling structure. In particular in the charging…
Quantum Mott transition in a silicon quantum dot
S. V. Vyshenski, U. Zeitler, R. J. Haug
Considering a double-barrier structure formed by a silicon quantum dot covered by natural oxide, we derive simple conditions for the conductance of the dot to become a step-like fu…
