Zero differential resistance in two-dimensional electron systems at large filling factors
A. T. Hatke, H. -S. Chiang, M. A. Zudov +2
We report on a state characterized by a zero differential resistance observed in very high Landau levels of a high-mobility two-dimensional electron system. Emerging from a minimum…
Non-linear Magnetoresistance Oscillations in Intensely Irradiated Two-Dimensional Electron Systems Induced by Multi-Photon Processes
M. Khodas, H. -S. Chiang, A. T. Hatke +4
We report on magneto-oscillations in differential resistivity of a two-dimensional electron system subject to intense microwave radiation. The period of these oscillations is deter…
Microwave Photoresistance in dc-driven 2D Systems at Cyclotron Resonance Subharmonics
A. T. Hatke, H. -S. Chiang, M. A. Zudov +2
We study microwave photoresistivity oscillations in a high mobility two-dimensional electron system subject to strong dc electric fields. We find that near the second subharmonic o…
Non-linear magnetotransport in microwave-illuminated two-dimensional electron systems
A. T. Hatke, H. -S. Chiang, M. A. Zudov +2
We study magnetoresistivity oscillations in a high-mobility two-dimensional electron system subject to both microwave and dc electric fields. First, we observe that the oscillation…
Magnetotransport in a two-dimensional electron system in dc electric fields
W. Zhang, H. -S. Chiang, M. A. Zudov +2
We report on nonequilibrium transport measurements in a high-mobility two-dimensional electron system subject to weak magnetic field and dc excitation. Detailed study of dc-induced…
Spin injection from perpendicular magnetized ferromagnetic -MnGa into (Al,Ga)As heterostructures
C. Adelmann, X. Lou, H. -S. Chiang +5
Electrical spin injection from ferromagnetic -MnGa into an (Al,Ga)As p-i-n light emitting diode (LED) is demonstrated. The -MnGa layers show strong perpendicular magnetocryst…
