Sub-linear radiation power dependence of photo-excited resistance oscillations in two-dimensional electron systems
Jesus Inarrea, R. G. Mani, W. Wegscheider
We find that the amplitude of the radiation-induced magnetoresistance oscillations in GaAs/AlGaAs system grows nonlinearly as where is the amplitude an…
Local investigation of the energy gap within the incompressible strip in the quantum Hall regime
E. V. Deviatov, A. Lorke, G. Biasiol +2
We experimentally study the energy gap within the incompressible strip at local filling factor at the quantum Hall edge for samples of very different mobilities. The obtain…
Measurement of spin-dependent conductivities in a two-dimensional electron gas
H. Ebrahimnejad, Y. Ren, S. M. Frolov +3
Spin accumulation is generated by injecting an unpolarized charge current into a channel of GaAs two-dimensional electron gas subject to an in-plane magnetic field, then measured i…
Imaging Localized States in Graphene Nanostructures
S. Schnez, J. Güttinger, M. Huefner +3
Probing techniques with spatial resolution have the potential to lead to a better understanding of the microscopic physical processes and to novel routes for manipulating nanostruc…
Spatially resolved ultrafast transport current in GaAs photoswitches
L. Prechtel, S. Manus, D. Schuh +2
We apply a pump- and probe-scheme to coplanar stripline circuits to investigate the photocurrent response of GaAs photoswitches in time and space. We find a displacement current pu…
Zero-bias Anomaly of Quantum Point Contacts in the Low-Conductance Limit
Y. Ren, W. W. Yu, S. M. Frolov +2
Most quantum point contacts (QPCs) fabricated in high-mobility 2D electron gases show a zero-bias conductance peak near pinchoff, but the origin of this peak remains a mystery. Pre…
Observation of excited states in a graphene double quantum dot
F. Molitor, H. Knowles, S. Dröscher +8
We study a graphene double quantum dot in different coupling regimes. Despite the strong capacitive coupling between the dots, the tunnel coupling is below the experimental resolut…
Electron-avalanche amplifier based on the electronic Venturi effect
D. Taubert, G. J. Schinner, H. P. Tranitz +4
Scattering of otherwise ballistic electrons far from equilibrium is investigated in a cold two-dimensional electron system. The interaction between excited electrons and the degene…
