Novel metallic and insulating states at a bent quantum Hall junction
M. Grayson, L. Steinke, D. Schuh +6
A non-planar geometry for the quantum Hall (QH) effect is studied, whereby two quantum Hall (QH) systems are joined at a sharp right angle. When both facets are at equal filling fa…
Microwave induced magnetoresistance oscillations at the subharmonics of the cyclotron resonance
S. I. Dorozhkin, J. H. Smet, K. von Klitzing +2
The magnetoresistance oscillations, which occur in a two-dimensional electron system exposed to strong microwave radiation when the microwave frequency coincides with the n-th…
Circular polarization dependent study of the microwave photoconductivity in a two-dimensional electron system
J. H. Smet, B. Gorshunov, C. Jiang +7
The polarization dependence of the low field microwave photoconductivity and absorption of a two-dimensional electron system has been investigated in a quasi-optical setup in which…
The Cyclotron Spin-Flip Mode as the Lowest-Energy Excitation of Unpolarized Integer Quantum Hall States
L. V. Kulik, I. V. Kukushkin, S. Dickmann +6
The cyclotron spin-flip modes of spin unpolarized integer quantum Hall states () have been studied with inelastic light scattering. The energy of these modes is significantl…
Microwave photoresponse in the 2D electron system caused by intra-Landau level transitions
S. I. Dorozhkin, J. H. Smet, V. Umansky +1
The influence of microwave radiation on the DC-magnetoresistance of 2D-electrons is studied in the regime beyond the recently discovered zero resistance states when the cyclotron f…
Zero-Resistance States Induced by Electromagnetic-Wave Excitation in GaAs/AlGaAs Heterostructures
R. G. Mani
We report the detection of novel zero-resistance states induced by electromagnetic wave excitation in ultra high mobility GaAs/AlGaAs heterostructure devices, at low magnetic field…
